I don't think it's a coincidence that the shittiest companies are those, who enforce Google's broken and monopolistic "Play Integrity" API. Revolut has connections to Russia, McDonalds supports the Israeli genocide in Palestine and Authy has always just been a massive piece of shit, not even allowing users to export their TOTP seeds. These are three companies I would NEVER even consider using anyway.
And "Play Integrity" API actually does NOTHING, absolutely NOTHING for your security as an end user.
You use an outdated, unpatched Android version with multiple severe, publicly known exploits on an insecure device?
Google doesn't give a single fuck.
You use the newest version of Android with all the patches applied on Google's own hardware, with a locked boot loader and a hardened operating system?
That's not allowed by the "Play Integrity" API.
It's only purpose is to serve Google's monopolistic business interests.
