Generally I think the issue is that there's a tension between your security vs Paypal's security (deliberate, motivated bad actors). Maybe an analogy could be about using metal detectors as a layer to reduce bank robberies. A gun in a good guy's hands is a good thing to prevent robberies. Guns in a bad guy's hands are a bad thing to prevent robberies. Paypal knows you have a gun but they don't know if you're a good guy or a bad guy so it's easier to just ban guns.

PayPal app still works on GrapheneOS. It's because PayPal shipped an update with incorrect anti-tampering code incompatible with secure app spawning. It can be worked around with the per-app secure app spawning toggle until they fix it. The first thing to try when an app doesn't work is trying the per-app exploit protection compatibility mode. That sets all the per-app exploit protection toggles to the compatibility mode. If that works which is likely the problem, it can be narrowed down. Nearly all Android apps are compatible with GrapheneOS. The exception are around 10% of banking and government apps which use the Play Integrity API to ban using a non-Google-approved device or OS. That's visible to users on GrapheneOS via a Play Integrity API usage notification. After the first use by an app, GrapheneOS provides a menu for blocking using the Play Integrity API which sometimes gets apps working because many don't enforce it working. It's not fully reliable and can have downtime so apps often don't enforce providing a result.

It was never about your security, it was about the corporation's security from you!

Might be more a matter of "OS with millions of users" vs. "OS with dozens of users".

Revolut pulled that stunt, I cancelled my account with them.
