Compromise on your computing freedom, compromise on your attention and privacy, when both providers are out to fuck you it doesn't really feel like you have a meaningful choice to make. Asking for an environment where fucking your customers isn't allowed feels like the only option.
I have a Pixel with Graphene on it. It's not de-Googled though, because Google successfully entrenched their services as a dependency of the majority of apps on the platform. Graphene makes yet another compromise by installing Play Services in a sandbox, which still lets it spy on you (but less) in exchange for enabling most (not all) Android apps to run. You can't really escape the compromises if you want a capable pocket computer. Compromises borne not of technical requirements or limitations, but of decisions that some of the largest companies in human history have made to fuck you.
Big fan of Graphene! The balance I personally prefer is to use Shelter to create a "work profile" and install Play Services in there along with any apps that must have Play Services. Then, I only enable the work profile when I need to use those apps.
I don't know about "factually incorrect" I believe this[1] is what the OP was vaguely referring to.
Apple says they're not doing CSAM scanning anymore, but there's no way to verify they're being truthful. And given everything known about corporate America, it would be foolish to believe them.
Unfortunately, you lose a significant amount of functionality by degoogling. Any app which relies on Google services, which is a large number, will be broken.
