Spain (nor any other country) doesn't have a say on what's allowed on the platform when it comes to its own citizens. That's supranational control. To use a throwback phrase form the old guard, it's "Imperialistic".

What if WeChat, if TikTok, etc., etc., went all out with CCP propaganda and undermined Biden on all things China with regard to their US users? What if they decided they wanted to back a friendly candidate and have anti Biden propaganda? Are we cool with that? Or are they only cool when they carry water for you?

Let's suppose Mark Z decided he wanted to forgo US citizenship and went out and got Russian citizenship and then decided it was okay for FB to carry his new message? Cool? Oh, oh, do I hear calls of "interference"?
