Since Ethereum transactions are easily censored, and transactions on other blockchains like Bitcoin and Monero aren't, they are just going to do what they got to do for coins like Ethereum and then for the other, more stubborn networks (as in 'we do not care what is being ordered as we are decentralized), they put extraordinary amounts of KYC through it or failing that, blackhole them from centralized exchanges and other platforms.
It's no good to be using a network where funds can be frozen. Then it just becomes a bank with no insurance and low payment penetration.
