Slow sites can be sped up quite often with small optimisations and improvements and those improvements can be guided by Google tools but instead they're forcing their own new format in the name of speed.
iTunes didn’t take over any existing service or stop you from doing something you could before on the web
Open standard, opt-in free cdn, independent compatible alternatives; this does not sound like a hostile takeover of your freedom.
Its the same reason why Apple never gets slapped with monopoly charges. You have the option of using Android for your phone (ignoring the fact that if you value your privacy you don’t) and Windows/Linux.

Does the user have the option of changing to DuckDuckGo? Yes. And moreover AMP can also be hosted totally by your own servers. See Guardian.com AMP serversiTunes has been selling non DRM music for a decade and you can transfer most purchased movies to other services using Movies Anywhere. The podcast directory is just that - a directory to podcast feeds. They don't host any of the podcast and provide an API.
Messages interoperare with standard SMS, MMS. You don't get all of the non standard features.
Personally I'm about as hostile to Apple News as I am to AMP for a lot of the same reasons. And I also don't love Apple's embrace & extend approach to SMS.
I guess there was a time when I was concerned about iTunes and DRM and the network effects of an Apple music ecosystem, but I mostly stopped buying stuff through iTMS that I could get elsewhere about a decade ago and then largely ditched iTunes somewhere around 5 years ago after Apple had spent so much time "revolutionizing" the UI that it became a shambling horror of a guessing game rather than an experience, and AFAICT these days there's plenty of ways to use Apple devices for listening to music without using any of their specific apps/services.
So, yeah, I'd guess there's probably a concerned audience that isn't exactly picking on Google while giving Apple a pass.
