In fact, demanding and ensuring complete control over the technologies we use is a pragmatic and entirely justified strategy for anyone who cares about their data, their computing capabilities, and even their quality of life.
I think it goes much further than that: the control Apple/Google/Facebook/... have over a large proportion of devices can give them sufficient leverage to make it possible for them to control you as well even if you don't use their services (e.g. by them arranging to have people elected which in turn introduce legislation or executive orders that impact you).
You might argue we're not there yet, but the Cambridge Analytica affair makes it pretty obvious that it's a real possibility.
