@einebiene Easiest step is to make sure that whatever culture you consume is an ideally permanent copy that you can keep around and view whenever you want (hard copies, downloads without DRM...).
DVD/Blu-Ray are not as bad as streaming. However, downloads with DRM stop working when distribution company:
* goes bankrupt
* misses out on updating some license
* servers gets hacked/unavailable
YouTube videos are generally ok in this sense since you can do 'youtube-dl' (until the "EME" stuff in HTML5 gets a stronger foothold).
Furthermore "EME" is rather explicitly realised as a direct cause from Netflix's demands, See https://www.defectivebydesign.org/netflix (which doesn't seem to have received netflix-specific content recently though).
@dbd has however moved to this page for campaigning against crippling the web: https://www.defectivebydesign.org/drm-in-web-standards
