TikTok, LinkedIn join Musk’s X in Ireland’s regulatory crosshairs - Big Tech faces fresh EU scrutiny
Dublin's data watchdog just expanded its regulatory dragnet—and Silicon Valley's biggest names are feeling the heat.
When Ireland calls, Big Tech listens
Forget Brussels or Berlin. When it comes to EU tech regulation, all roads now lead to Dublin. Ireland's Data Protection Commission holds disproportionate power as the lead EU regulator for countless multinational tech firms—thanks to their European headquarters clustering in the low-tax jurisdiction.
The expanding investigation list
Elon Musk's X platform was already under formal probe for potential GDPR violations. Now TikTok's data transfers and LinkedIn's targeted advertising join the scrutiny list. The DPC isn't just sending warning letters—they're launching full-scale statutory inquiries that could result in fines worth billions.
Why this regulatory wave matters
Ireland's sudden enforcement surge signals a tectonic shift. For years, critics accused the DPC of being a 'paper tiger'—all bark and no bite when it came to actually penalizing its corporate residents. That era appears over. The commission now faces pressure from both European counterparts and privacy activists to demonstrate real enforcement muscle.
The compliance domino effect
Every decision from Dublin creates precedent across 27 member states. When Ireland fines a platform for unlawful data processing, every national regulator gains ammunition for their own investigations. It's regulatory arbitrage in reverse—one jurisdiction's strict enforcement suddenly becomes everyone's problem.
Broader implications for digital markets
This isn't just about privacy fines. The DPC's actions directly impact how platforms monetize user data, target advertising, and design algorithms. Stricter enforcement could force fundamental business model changes—potentially hitting revenue streams that Wall Street analysts treat as sacred cows.
The cynical finance angle
Here's the delicious irony: those same tax advantages that attracted tech giants to Ireland now work against them. They saved billions in corporate taxes by headquartering in Dublin, only to face regulatory oversight from the exact same jurisdiction. Call it a regulatory boomerang—the bill for those tax savings might finally be coming due.
The message to tech boards is clear: your Irish headquarters just became your biggest regulatory vulnerability. And for investors banking on uninterrupted data monetization? Better factor in some Irish rain on your growth projections.
Ireland investigates TikTok and LinkedIn
According to a Bloomberg report, Ireland’s media regulator investigations into TikTok and LinkedIn are happening over potential flaws in their content reporting mechanisms. The probes will focus on ascertaining whether the platforms’ systems for users to report suspected illegal content are adequately accessible, user-friendly, and anonymous, as required by the DSA.
Providers need to “have reporting mechanisms, that are easy to access and user-friendly, to report content considered to be illegal,” said John Evans, Digital Services Commissioner at the regulator.
The European Commission is the main European Union enforcer against very large online platforms. However, some aspects of the law — including the reporting mechanism — fall under the jurisdiction of the national regulator of the EU country where a platform is headquartered.
Companies found to be in violation of Europe’s digital rules, as determined by Ireland’s media regulator, can be fined as much as 6% of the company’s annual global sales.
This is not the first time the Irish regulators have targeted a social media platform. TikTok was also caught in its crossfire and got slammed with a €530 million penalty for violating the EU’s General Data Protection Regulation (GDPR) in May 2025, while LinkedIn also got fined about €310 million for various regulatory breaches.
Ireland’s media regulator is also after X
The current investigations into TikTok and LinkedIn are coming weeks after the same regulator opened an investigation into Elon Musk’s social media platform X, with claims that the company is failing to remove content users report as illegal.
According to Virkkunen, the Executive Vice-President of the European Commission for Technological Sovereignty, Security, and Democracy, while the DSA requires platforms to enforce content moderation, it also requires them to have effective internal complaint-handling systems, where users have the right to appeal content moderation decisions.
“While automated moderation is allowed, online platforms must be transparent about its use and accuracy,” Virkkunen added.
Investigations by Coimisiún na Meán seek to determine if X’s internal complaint handling system is up to par with the DSA’s regulatory standard or is in violation of it. The investigation is backed by various sources, and a nonprofit HateAid, which had previously made legal moves against X on behalf of a researcher who was repeatedly banned from the platform.
The investigation was the first under DSA by the Coimisiún na Meán, and violations could result in almost 6% of the company’s turnover. It is also not the first time X has attracted scrutiny from official bodies in Europe. Earlier this year, the platform was investigated by the EU over whether it breached the bloc’s content laws.
Experts believe the scrutiny could inspire broader changes in X’s operational and content moderation policies. Meanwhile, the recent investigations are a clear indicator of how far the EU is willing to go when it comes to holding social media platforms accountable and ensuring that user protection measures are robust and enforceable.
