It's even worse, as they actively degrade the features you use.

With movies and music in the mix, international licensing agreements needs to be respected.

In short, I paid for YouTube premium to avoid ads. Then I travelled to another country where YouTube didn't have licensing rights for all of their movies and music, so my premium account was just disabled completely and I got ads again.

You can fix that with a VPN service, or by creating your own VPN network. You could buy a Digital Ocean droplet in your location and connect to that like a VPN.

1 - this is not a solution, it's a workaround. an adblocker solves the issue much better

2 - DO vpns are blocked (almost) everywhere

Are you asking people to pay additional money to a third party service so that they can continue to use a service they have already paid for and should be fixed by that service provider in the first place? Don't you think this is ridiculous?

Genuinely curious: if you bought YT premium mainly to block ads, why not just use Ublock Origin along with something like NextDNS?
