Nearly everything you've said was bullshit. Google has never restricted sideloading. Android 12 even enables sideloading further by allowing third party app stores to auto update. AOSP exists. Third party roms exist. All of the devices sold by Google can be unlocked to install third party roms. LineageOS doesn't exist because 'a complete and unassailable monopoly' allows them to.
Google admits it tries to prevent sideloading as much as possible in their own court filings with Epic. Their own managers called the experience "abysmal", and they considered buying Epic to prevent them from doing it. Also they sent Project Zero out to portray Epic as "insecure" in a bunch of hit pieces across the media. AOSP is not meaningfully existing on any device sold today.

AOSP is technically sold on every device since that's what every single Android version *AND* skin is based on.
If you want to do something that isn't supported by the oem, then do it yourself. Nothing stops you from being able to do so which is the entire damn point.
> The fact you can hack your device doesn't change the monopoly Google operates that 99.9% of Android devices are trapped in.
An unlockable bootloader isn't a hack. Try again.
For an IT Consultant, you're remarkably ignorant when it comes to the reality of Android.
