Literally insane that banks will allow you to do banking on ancient phones with an unpatched Android full of CVEs, but won't allow you banking on a modern ungoogled OS.

It's not about security, it's about lazyness. These are the people who still employ Cobol devs cause they don't want to migrate off existing mainframes. I've yet to see a banking app that was not an objective trainwreck.

Dont confuse intent with laziness, running on cobol genuinely gives them many advantages.
