I think the solution is to convince more people that we can live happy lives without access to big-budget entertainment. I've been mostly going without for about two years now, though I've wavered a few times.
IANAL but seems to me like laws along the lines of "you can reverse engineer DRM without being arrested" and "the patent holder/whatever of the DRM cannot deny you a license to use this without a good reason" seem like the right direction to me. Then the linux distros or anyone else can go off and build/integrate the DRM to the extent that they wish.
Because Widevine is so widespread and acts as a gatekeeper for content (for example Netflix), if Google doesn't bless your platform with Widevine support you're essentially dead as a consumer media platform.
Google should not have this kind of power because competition is good.
