Are there organic movements in Germany, UK, USA, Norway etc of common citizens agitating for social media controls for kids? Are they actually composed of citizens? Are they funded by grassroots organizations? I can tell you that in the USA there are basically no real grassroots efforts to censor social media, at least none with a real footprint that most people have ever heard of. Despite that, there are a lot of politicians making laws to clamp down on social media use.
I think most people can intuitively see that the number of people who talk about this as an issue does not at all match the amount of attention that politicians are giving it. All at the same time, in most western countries simultaneously. It just does not pass the smell test.
>you're going to think spooky coincidences are happening.
Nothing spooky about it, they are not coincidences, we can see that ideas are spreading between powerful politicians and the billionaire oligarchs across borders without any real input of the governed. Laws are being made, we are being given the "think of the children" line, and they are hoping that we will accept it.
Just because we can communicate across borders doesn't mean that countries should stop considering the needs of their citizens as their primary objective. The more we allow these efforts to cross borders without any objection or examination, the weaker the power of citizens becomes and the less effective democracy becomes.
