I'll be very interested to see what happens when it's countries they have more connections to, who start doing this kind of thing.
For example in the UK it seems likely that the Digital Verification Act will require ISPs to block access to pornographic sites that don't comply with the legislation.
Given the rise of DNS over HTTPS, it'll be hard to comply with that requirement without some form of MITM, so if the UK ISPs do that, will Mozilla/Google/MS/Apple also block their certs...
