The European Union is once again looking for ways to expand its regulatory reach over online speech. A 275-page study commissioned by the European Commission, published on April 29, 2026, explores the feasibility of forcing major social media platforms—including Elon Musk’s X, Facebook, Instagram, and YouTube—to implement both vertical and horizontal interoperability. Irish Gript explains:
[T]hese platforms could be forced to platform content from their more moderation-focused rivals, as well as be legally obligated to make their recommender algorithms, news feeds, and user accounts interoperable with websites more favoured by Brussels, such as BlueSky.
On the surface, the proposal sounds benign: greater “user choice,” reduced “monopoly power,” and a more “open” internet. From a free speech standpoint, though, this could limit X’s relatively open environment and import Brussels-approved standards of ‘safety’ and ‘systemic risk’ mitigation into users’ feeds.
The Digital Services Act (DSA) already imposes heavy obligations on ‘very large online platforms’ (VLOPs) like X. It demands transparency on recommender systems—algorithms that suggest content to users based on what they’re likely to find interesting—options to opt out of personalized feeds, and rigorous risk assessments for ‘disinformation,’ illegal content, and societal harms. The Commission has aggressively enforced this against X, launching investigations into its algorithms, issuing a €120 million fine in December 2025.
‘Interoperability’ for online platforms would take this a step further. The study assesses the technical and legal feasibility of requiring platforms to make their core functions—algorithms that determine what users see—interoperable with services that align more closely with EU preferences for proactive moderation of ‘hate speech,’ ‘disinformation,’ and polarizing content. The mainly leftist-liberal social media platform Bluesky is repeatedly cited favorably for its plugin ecosystem, where users or third parties can apply heavier ‘curation’ layers. This would give the EU the opportunity to inject its favored content prioritization or moderation signals into X feeds under the banner of ‘choice.’
Free speech advocates see this as an indirect censorship mechanism. Rather than outright banning posts, the EU could with these tools reshape their visibility, normalizing stricter European norms globally. The EU’s track record—raids, fines, and pressure for preemptive censorship—suggests ‘user choice’ would be heavily steered toward compliant options.
X has resisted, appealing the €120 million fine and arguing the DSA stretches into compelled speech territory, showcasing the divide between the right to free speech of the U.S. Constitution’s First Amendment and the European model, which seeks to balance speech rights against collective ‘safety’ and harmony.
If implemented, these plans would risk erecting a ‘digital Iron Curtain,’ where European standards subtly colonize global platforms. Interoperability could risk becoming centralized control by another name. But for now, the study suggests a wait-and-see approach: keep a close eye on how existing interoperability rules are working and how people’s use of social platforms continues to evolve.
