I suspect a lot of it comes down to your ISP. Like the original commentor I also frequently can’t pass CloudFlare turnstile when on Wifi, although refreshing the page a few times usually gets me through. Worst case on my phone’s hotspot I can much more consistently pass. It’s super annoying and combined with their recent DNS outage has totally ruined any respect I had for CloudFlare.

Leaving ADB open to unverified apps is more than I was expecting. ADB is reasonably straightforward to use even without actually being an Android developer.
There was never any way they’d integrate it to play protect and still allow play protect to be disabled. I prefer this to being required to use play protect personally, though the services do seem somewhat redundant. Presumably the whole point of doing this is to create an Apple style walled garden (which is of course very profitable). Google likely doesn’t want to fully lock it down and risk legal trouble, they just need to make it difficult enough that the masses don’t bother installing unapproved apps that may not act in Google’s interests.
I still hope the EU takes legal action against this anyway.
