Lol, I mean banks already require KYC and have your real identity on record so you could just use it on your phone running the official corporate-built mobile os, I mean my point is, you aren't even supposed to use VPN for online banking cuz they'll just flag your connection, that connection is supposed to look as "normie" as possible (hence why it kinda breaks with graphene os). I'm talking about activities that you were previously using GrapheneOS/Custom ROMs for, like the stuff you want privacy for.
