This so much. I'm lucky enough to be able to afford enough streaming services to cover the majority of what I want to watch (although that's changing for the worse over time). I just want to pipe them all through Kodi or some other software into a unified interface that is media source agnostic, that can also stream the content in the best quality available for my screen.

At that point the content is already paid for, I don't need to use your own individual reinvention of the interface that inevitably focuses on pushing uninteresting content instead of making it as easy as possible to continue what I've already started watching or to find what I want.
