I'm a bit curious about how that works. I love Mullvad but routinely I find sites like Reddit completely block it. Even yesterday someone posted a Debian wiki link[0] and I was blocked. It's not all of them but Reddit is a big killer. So I thought China would block all of them (aren't they known?)
Fwiw I'm not switching from mullvad
