It’s not if you’ve paid attention to political trends for the last 15 years.

Everything is happening at the same time in every country. It’s clearly being coordinated.

Btw, it doesn't need to be actively coordinated for this to happen.

Building architectural styles used to be per city and now buildings look roughly the same worldwide. Style is dependent on the year built not the location.

Because every architect is "reading the same magazine" worldwide now that the internet exists, rather than debating in their own city.

Similar monoculture of global thought is happening in all fields.

It's almost like a well-monied or well-connected lobbyist is pushing this heavily. Multiple contenders out there as to who it could be. But regardless of who the originator is, the push can be kneecapped. Imagine jurisdictions that have an opposite push - one that criminalizes use of age verification software such as mandating providing government ID or facial scans. It can be done!

Well obviously? It's literally being broadcast in the news when diplomats talk to each other. What do you think they are talking about if not policy discussions?

My guess would be some very influential NGO(s). But I haven't looked into it or thought about it.

The simpler explanation is that we live in a world that is more connected than ever so politicians, campaigners and the rest can get policy ideas almost instantly. There is no grand conspiracy, just a smaller world.
