“They can come down on you for a lot of things. They seized up the bank accounts for people who were protesting, the truckers. People who were donating to the truckers, they seized their bank accounts,” Rogan said.

I don't know what "a lot of things" is gesturing at, maybe he doesn't either. Use of payments censorship to shut down protests without legal proceedings is legitimately worrying, though this is something right wing commentators tend to fixate on to the exclusion of the same stuff when used against people who aren't their audience. Here's an article that I think has a good perspective on this.

All these cases happen somewhere distant to a person in the US or Canada, so could it be that the Truckers struck a nerve because this was the first time that citizens of a democratic Western nation were subject to payments oppression? The answer is no. Cashless payments censorship has a long and established tradition in Western countries. It’s just that it’s not recognized because it’s been focussed on marginalized groups such as welfare recipients.
