I think it's more that they are DRM obsessed and don't give two flying ducks about Linux. If Linux were important, their DRM would work on it. For one I blame them, for the other I don't.
I have to admit I just don't care that much anymore. In the spectrum of things I have the time and energy to really care about, DRM has fallen off the list. I want to watch The Mandalorian, and damn; it was pretty great.
