It wasn't even limited to those who actually broke any laws. Multiple incidents have been reported by Canadians who donated as little as $50 to the protest BEFORE it was declared illegal, having their bank accounts frozen without any formal charges.
Given that they are not even charging these people with crimes, they are denied due process and their economic lives are destroyed for the crime of committing a lawful act that happened to be unpopular with the ruling party.
To portray this as a reasonable step to curtail foreign influence in domestic affairs seems intellectually dishonest. This was government overreach pure and simple.
