What’s more far ahead than an ecosystem that you can’t leave without replacing all devices because they work poorly with anything other than Apple. If you don’t like all their products or Apple makes changes that you disagree with then sucks to be you, I guess.
For my use case of simply wanting to have myself and my wife on a custom domain email, this is still unreasonably expensive. I don’t care about the other offered services as I have everything else that I need running on my own server but email is safer to run off premises.
