Might also depend on how it’s enforced. The blocks in Austria basically do not exist because they are only done by carrier DNS servers. Use 1.1.1.1 or 8.8.8.8 and you would not know.
I don’t think that is relevant here. If in one country you need a VPN to bypass blocking but others you only need a different DNS server I would expect most users to go for the latter if given a choice.
