For what it’s worth, my understanding is that widevine is terrible, terrible software. Its purpose is to take away the freedom of technology and people. No one should use widevine, on a Librem 5 or on any other device.
I can understand circumstances where people have no other option and need to use it, so I’m glad for the collaboration on this thread. Just thought I’d throw in my two cents, in case someone reading this thread isn’t aware.
