They probably do. FDroid isn't available on the play store, so this is not a great example. But if an app on the Play Store tripped the warning, it would look really bad for Google if they show this warning because it says "we know this software might be dangerous and we're hosting it anyways."
Malware exists on the Play Store, but either Google turns a blind eye (too risky. It'd be _really_ bad if someone proves it), or the devs engineer the malware to dodge the safety tests.
@m3lang3 @apps this warning is mostly in place for the Email scammers that say "You need an updated version of your banking app. Use this link." And then they give the victim an APK that trips the play protect warning.
It makes this kind of scam way more difficult to pull off since not only does the victim need to enable installing apps from the web, they also need to convince the victim to ignore the big "THIS APP IS UNSAFE" warning.
