Meh. I didn't reflash my phone. I didn't root it. I didn't do anything to modify its system files whatsoever. I just installed KDE Connect, and an open source keyboard. Banking apps refuse to run because of those (because my keyboard might see my keystrokes!!!). They don't even need a failed hardware attestation to refuse you service. So even if you don't try to modify your device, your device might still end up like…

A motivated individual with the right tools and hardware hacking know how may be able to jailbreak a screen to record stuff, but that's going to make things out of reach for most people.

It's not common anymore, but _way_ back in the day, some releases were made *in the projection booth* with a semi-pro camera on a tripod pointed at the screen. (look for old NFO files with `TS` or `TeleSync` in them to get an idea of when this was common-ish) The…
