What you're seeing is a coordinated push by transnational interests; Meta's name has come up in discussions of the funding behind this push. At the very lest, verifying age also verifies that a person is real and not a bot, so advertising firms like Meta will benefit from verification. That's not right-wing or left-wing but rather the influence of business over the political, and neither wing of the spectrum is immune to corruption.
Isn't that basically every democratic country?
We can't judge how "right" or "left" the political culture of a country is by how frequently the right or left win office, because in the long-run they tend to win office roughly equally often just about everywhere.
A better way of judging this question, is how the policies of their main left/right parties compare to those of their counterparts in comparable countries
I'd classify both as very corporate friendly, far centrist, which is just as good as "right wing". Nothing about actually empowering the masses, and even less so the working class, only elite pseudo prograssive talking points.
In the US both the Democratic Party (Liberal) and Republican Party (Conservatives) are considered Authoritarian on this 2 dimensional graph.
Milei claims to be a Conservative Libertarian so, in theory, he should be opposed to this. We'll see what he actually does.
That's just for the gullible. In practice he's about power and self-serving interests, just like any "libertarian" in office.
