Not that I've seen and I'd take what Purism say with a grain of salt: they've acted like pretty shitty gatekeepers themselves. Nothing they mentioned in the article seems too egregious in truth and they're exaggerating the scale of it: Play Store app DRM exists already, and the restrictions on browser-downloaded apps they mention can be bypassed (albeit by having to go into settings) and don't apply to apps installed through other apps stores (F-Droid, etc).

I haven't seen proper reporting but the Play Integrity install source thing is accurate. There's a reasonably good overview straight from the devil himself.

Lots of things that have very valid reasons on paper that also just happen to give Google a stupid amount of control and will backfire for a somewhat small percentage of people in very bad ways. We've been at "you can't use pretty much any bank unless you agree to either Google or Apple terms" for quite some years now, now we're giving those same app developers ways to detect if their device has accessibility APIs enabled (useful to protect against bot farms, but also a functional check for "you're able-bodied") or is in security support (also a functional check for "not reliant on hand-me-downs").
