Like Apple Music?
Each phone vendor including Apple does this to some extent. On Android you at least have some options (I had a few of them all were very close to stock), and usually you can disable these apps if there are any.
Worst I had to deal with was shortcut to OnePlus community forum, which is arguably less offensive than Apple Music, which is often reported to bind to the Bluetooth play button.
As for services that 'demand' you install something, the option exists on Android and no one demands people install things on their Android devices. Why would iOS be different?

1. It is used now. 2. Google is a lot less aggressive than apple (see meta vs ATT).
Sure it’s not “forced” like you go to jail or your phone doesn’t work, but you can’t use the way 99% of people will get their games.
