Due process is a concept that applies (or is supposed to apply) to governments. It does not apply to private financial services companies. Politicians have realised this and are now aggressively and vigorously violating it by stepping outside the regular judicial system and simply scaring banks/card companies into stopping business with anyone said politicians don't like.
It wasn't Russia that started this trend. It was America.
But any entity which fulfills the functions of a bank will pose these problems, especially with high market penetration...
At least in the West there is something like due process, which is enough to put an upper limit on the abuse these companies can dish out.
