At least for now.
I'm not aware of any major issues this has caused.
The trust isn't the issue. Google and Apple has made DRM easy for these companies to integrate, and therefore they do it. There isn't more to it than that.
Decades of desktop malware used to drain bank accounts are not a major issue?
In any case my bank has not banned the use of Linux to do homebanking. Why? Because there isn't a easy to plug-and-play API to do DRM and remove consumer rights. This is largely for historic reasons, but there is no reason a FOSS mobile OS couldn't work.
