What kind of actions can gentoo do with your financial accounts, and what levels of user authentication does it use to do it? My phone can effectively act as a bank card with contactless payment or I can transfer up to a daily allowance (that would be painful to me if it was misused) of thousands with biometric auth. Similar to the OS if you're doing that with any browser with a web login you could potentially compile it to behave how you like or lie about what it's doing
Because it's a bank there's going to be insurance behind the scenes to cover them if something goes wrong, and I assume part of that is ticking off enough points to be confident a transaction is secure or different payment limits on confidence levels.
I disagree. I don't understand how it's fine that I can access my banking services with my Gentoo machine, with everything compiled from source by myself, but it's somehow a problem when I'm not using either Apple or Google certified OS on my phone.
I'm sure they want to prevent the first scenario, like various streaming cartels already do, but I hope something like EU throws a fit if they do.
