Starting September 30th, there’s going to be a tsunami of Android users looking for an alternative system fleeing this developer verification malware.
In your opinion, are things like post market OS and the rest of the Linux phone ecosystem ready to take on these new users?


Yes.

But I’m with OP here; I simply use my browser, I don’t even want to install my bank’s app (it’s listed as working well).
if the bank has the same functionalities on web. Spoiler alert, they don’t. Credit cards need to approve online transactions on the APP, not website. Bank website has pretty much only kyc info, no payments.
On the plus side there’s an app on that list that I could move to.
