As a pp mentioned, it's happened in Canada too, to the truckers when they were protesting against covid rules.
It's also happened to organisations, like the Reclaim party, and it's happened to various fundraisers for women's rights. Obviously not the same as stopping individual's accounts, but what's to stop a bank from cancelling the account of someone associated with a women's rights campaign? The case reported on in the OP sets a precedent.
It's just fairly stupid to assume that if governments or corporations have this sort of power that it's always going to be used in our favour, in line with 'our' beliefs.
And the Chinese social credit system is already starting to happen here and it's incredibly sinister. I don't know what to say, OP, but people on here seem to be well behind on all this stuff, or as a pp says, they're kind of into it because they assume they're always going to be on top.
