For those of us in the US, there is a bill in congress right now that would make it illegal for any financial service provider to directly or indirectly prohibit or inhibit any legal transaction. In otherwords, a direct fuck you to these puritanical cunts. It's called the Fair Access to Banking Act, H.R.987 in the House, S.410 in the Senate.
You don't have to convince your rep or anything, you just give them a call, say you support and want your rep to vote for this bill and add your voice to the list. That's literally it. Call your representatives. Get it passed.
Hell, if I was a game dev, I'd probably be putting a notice in my games for this. Wish F95 had a notice too. It's that important. For everyone else, feel free to copypaste this as you see fit in other threads, and spread the word. We can fight this.
