I don't really understand, I don't get ads on my Android phone?
And I'm not sure what you mean about ecosystems either, yes you do need a Google account to download apps from the Play store, but you also need an Apple account to use the Apple store as far as I know.
In my experience it's easier to create a second Google account than a second Apple account.
Now I'm not representative of most users, like all HN users probably. But at home, apart from my M1 Mac (running Linux because I hate macOS) my other machines are Intel n100-based. They work fine.
Android is preloaded with different flavor of crap depending on the vendor and side-loading a phone OS and dealing with everything - I just don't have the energy these days. Likewise for running Linux on top of a M series Apple device. My devices just work and they all work together - all I have to do is login to the same account. My phone shares stuff with my Mac without any setup - shared clipboard, apps, storage. Buds connect to all my devices, Mac Mini, MadBook, iPad - not just 2 BT devices at a time, and they switch seamlessly. Stuff that saves me time and just does what I want. And all of the devices are usually among the best in class individually.
Nobody outside of Apple even has that as a vision. Microsoft is so bad at building consumer products it's unbelievable. Google is struggling to build compiling phones with its own software - I doubt they can execute on other device types. Valve did a relatively small investment in this ecosystem and brought it forward light years in the gaming space.
