It's not just the US though, EU too.

I don't like far fetched conspiracy theories but I really want to know where all this is coming from. Did politicians suddenly all get the same idea or are there groups lobbying for this who benefit in terms of money/power?

The EU has different norms. Bafflingly to me, it feels like the EU had an existing expectation of linking everything you do to your full name and address and then trusting the police to stop you getting swatted. I don't understand this attitude myself but you can see it in impressum laws for example, business registrations, needing your personal info to give feedback to parliaments, it's clearly a pervasive social norm over there. I suppose the reason they don't get swatting is that the police will verify the ID of the person who calls in the report.

It's the whole world.

I'm sorry to tell this, but everyone will soon realize that the far-fetched conspiracy theories are in fact severly underestimated conspiracy practices.

If they still have any remaining gut to face the reality, that is.
