I view Apple in much the same way. I don’t trust most developers, and part of what makes me willing to go out on a limb and throw a bit of money their way is the knowledge that I’m not gonna have to go through a whole path of dark pattern bullshit when I want to modify or cancel my subscription.
So I disputed the charge with my real bank, which corrected the problem by refunding me.
Google told me that if I ever did that again, they would lock me out of not just my account, but any future account using Google payment methods that was linked to me. That would make my phone service and the Google Play Store unusable. That was the beginning of the end of my relationship with Google services. So yeah...I do not trust Google or Apple as intermediaries for every payment in my life.
If a DRM store drops your account, you often do. (I think some of them do have a limited account type, so they will no longet let you transact, but you can still use the content you didn't chargeback)
There are no other companies you can go to to get an app on your iphone.
They are saying the middleman gatekeepers are dangerous becasue if you push them too hard they can take away your access to everything. Whereas if your agreements are with the individual companies and developers then the worst they can do is take away that one app.
