Quick shout-out to Grayjay: An app to watch videos on any platform - reducing the power of individual services. The Software is open-source and can be found here: https://gitlab.futo.org/videostreaming/grayjay
I will test this out for myself and hope someone here finds this useful.
The lesser of two evils is Android as it's like they put closed-source software on top of open source software (see AOSP) whereas on iPhone it's all closed.
