Brussels puts TikTok's recommendation engine in the DSA firing line, police detain 150–200 protesters at a Microsoft data-centre site in Amsterdam, and Europe's defence, aviation and energy-storage start-ups bank fresh capital. Here are the five European tech stories that matter this Saturday.

1. Brussels says TikTok's "For You" algorithm breaches the DSA and opens the door to a fine

The European Commission has issued preliminary findings that TikTok's recommendation algorithm is incompatible with the Digital Services Act, accusing ByteDance of pushing users into "rabbit hole" loops that amplify harmful content — a step that can lead to a fine of up to 6% of worldwide annual revenue.

According to heise online, Commission Vice-President Henna Virkkunen said that every scroll or "Like" feeds users more of the same material and traps them in a loop they cannot easily leave. The Commission argues that ByteDance has not done enough to curb the mass distribution of content with negative psychological effects, including when watch-time is used as a recommendation signal. Ireland's DSA supervisor, which oversees TikTok's EU base, was involved in Friday's findings. The case forms part of proceedings opened in February 2024; a separate preliminary finding on addictive design (infinite scroll and autoplay) was issued in February 2026. TikTok now has a chance to reply before any fine is imposed.

Why it matters: Regulators are no longer only arguing about illegal content or child safety features. They are attacking the "more of the same" logic at the centre of short-video engagement. A confirmed finding would set a template for other very large platforms whose feeds work the same way.

2. Police detain 150–200 protesters after activists breach a Microsoft data-centre site in Amsterdam

Dutch police detained an estimated 150 to 200 people after protesters broke through fences at a Microsoft data-centre construction site in Amsterdam-West, climbed a crane and the unfinished roof, and were later removed by riot police.

NOS reports that Fossielvrij had organised a permitted demonstration against data centres — some of which still run on gas — on a designated spot. A second group of activists then forced entry with grinders and climbing gear; police say they intervened after repeated calls to hand over the equipment failed. Hundreds of activists reached the yard, according to the police account. Officers later found property believed taken from the site among those arrested, and overnight custody decisions were pending. The suspects face trespass charges.

Why it matters: Local resistance to hyperscale AI infrastructure is no longer limited to planning hearings. A mass arrest at a live Microsoft build in Europe's densest digital hub turns grid, climate and geopolitical objections into an operational risk for operators and their lenders.

3. Portugal's TEKEVER picks Odense for its first Nordic base as Denmark's EIFO puts nearly €13m into its $580m Series D

TEKEVER will open its first Nordic operational presence in Odense after Denmark's Export and Investment Fund (EIFO) committed nearly €13m to a new closing of the Portuguese defence-tech company's $580m Series D, valued at $6.4bn.

EIFO said the commitment follows a meeting in Copenhagen with defence minister Jeppe Bruus. TEKEVER, whose AI-centric autonomous air systems have logged more than 50,000 operational flight hours in Ukraine and hold programmes in Germany, the UK and Portugal, is creating a Danish entity and will expand in phases subject to demand and approvals. Odense was chosen for its drone and robotics cluster, including Odense Robotics, UAS Denmark's test centre and the University of Southern Denmark's drone facilities. EIFO has already put about €134m into defence and security equity and more than €67m of financing into 20 companies, and wants annual activity to rise from €40m in 2024 to €400m by 2030. The Series D's first close, led by UC Investments and Baillie Gifford, was announced on 23 September 2026.

Why it matters: State capital is being used to pull European dual-use manufacturers into national industrial ecosystems, not just onto balance sheets. A Portuguese unicorn planting itself in Denmark's drone capital is a concrete test of whether Nordic procurement and testing capacity can absorb continental scale-ups.

4. Munich's VÆRIDION raises €30m and wins selection for a €94.5m EU Innovation Fund grant

VÆRIDION has closed a €30m Series A2 led by SHIFT Invest and Invest-NL to build the first conforming nine-seat Microliner prototype, and has been selected for a separate €94.5m EU Innovation Fund grant to industrialise final assembly at Oberpfaffenhofen — subject to a grant agreement expected in 2027.

Aviation Week reports that existing backers World Fund, Project A and Vsquared Ventures joined, as did PAYBACK founder Alexander Rittweger. Including earlier public money, equity raised is about €60m; the grant is on top. The all-electric Microliner targets 400 km with nine passengers under IFR, or up to 550 km with four under VFR, and is designed to EASA CS-23 rules. The company has completed preliminary design review and a second EASA pre-application contract, powered on its electric engine at Oberpfaffenhofen, and says it holds conditional orders for more than 130 aircraft worth over €730m, with ASL Group as launch customer. Commercial service is aimed at 2030. CAROLUS was one of 12 large-scale projects selected from 358 applications and the only aviation — and only German — project in that category.

Why it matters: Europe is trying to turn climate-tech grants into actual aircraft factories. A conforming prototype plus a nine-figure industrial grant is a rare pairing; the open risk is that the grant agreement slips and certification for novel battery-wing propulsion takes longer than the 2030 target.

5. Stockholm's Green Voltis raises €13.5m Series A to trade battery storage — and power AI data centres — with AI

Green Voltis has raised €13.5m in a Series A from sole investor Lochpine Capital to expand Aether AI and Chronos, its trading agent and energy-management stack for more than 1.2 GWh of European battery storage, and to build a Power-to-Compute pipeline of about 120 MW of Nordic powered land for AI data centres.

EU-Startups reports that the Stockholm company, founded in 2024 by Martin Kievit, Ali Shi and Gino Zhang, covers grid connection through to multi-market trading. Chronos is grid-code certified and supports grid-forming operation; Aether forecasts prices and stacks revenue across day-ahead, intraday and balancing markets. The firm says managed assets have outperformed the Clean Horizon battery-revenue index and that market access is live or underway in 10 European countries. It argues that grid connections in major European data-centre hubs can take seven to ten years, and that regulators from Ireland to Finland are starting to require new centres to offer flexibility — a gap it wants to fill by running sites as grid-friendly assets with compute partners.

Why it matters: Power, not chips, is becoming the binding constraint on European AI capacity. A storage optimiser pitching itself as the software layer between the grid and compute is a direct bet that flexibility revenues and data-centre interconnection will converge.
