>You seriously think Russia's state services are not compromised by intelligence?

The state services are required to assist intelligence and law enforcement in lawful investigations, the intelligence don't need to compromise anything.

>Why would you want your government to be able to track every single website you've ever visited

I don't want anyone to track every single website I visited.

>considering we're talking about an autocratic regime

Glad you see the EU for what it is.

The problem is that verifying age requires disclosing your identity and the fact that you use a certain service. Whoever is the provider of such verification, it learns too much about you.

Is the state a worse choice for that than a commercial entity that has fewer resources to secure itself against hacking and might even sell the data itself?

I would rather not have age verification at all and glad there is no such thing in Russia (yet?).
