Yes, and serious voices have been calling for that since at least the Cambridge Analytica scandal. This is especially true now that the owner of X is openly calling for major political changes in the EU.

This only makes sense. People correctly understood that foreign media organizations are a risk to self-governance and the tech companies which took much of their power should be treated the same way.

They should have done that.

Facebook and X are not directly controlled by the US government like TikTok is.

The American government, even today, simply does not have comparable cooperation with private companies. If Facebook and Twitter decide one day that they’ll no longer permit people to post mean things about American political leaders, a policy that is at least routine and I think universal in China, I think it would be a no-brainer for Europe to ban them. (Even if they release a special global version of the app that they promise isn’t subject to domestic censorship rules.)
