I have a maybe-conspiracy theory.

Israel, or Israeli citizens who were former IDF, have recently bought up a huge portion VPN companies (see outdated relationship with eachother here)

Now, conveniently as it happens, now age verification on porn sites (one of the top VPN drivers) is occurring all over the globe, in a lot of countries lobbied/bribed heavily by Israeli entities.

It is well documented that Israel has one of the largest and influential spy networks and they also have their hands in almost every mass surveillance company in the world (including having a “director of Zionist interests” at Facebook)

I think this is a big push to get everyone onto VPNs that they own to essentially route all internet traffic through a place where they can log and track all of it as they would benefit massively both financially and politically from that move.
