Everything aside from apps with SafetyNet dependencies. Banking apps come to mind.
Sure, but who would use a banking app when the web site is right there and has more features and generally works better?
Soo many more things than banking apps at this point. Things as normal as looking at train schedules, grocery store catalogues, ordering a taxi... sometimes have SafetyNet DRM.
When you publish apps on Google Play, the Play Developer Console even nags you to use harder obfuscation and implement Google's DRM to, allegedly, protect yourself and your users.
Can the EU finally make this shit illegal? Oh wait, they're pusing for mandatory DRM too... Fuck.
Banks want your money so try it anyway. Not all banks try to drive away their customers by preventing them from accessing their accounts.
Also, a lot of games. This is actually why I stopped playing Pokemon Go, and never picked up a worse gacha game habit haha
