DRM isn't the only problem. Watermarks are as well, they ruin the sound quality. Its a bit disappointing FSF doesn't mention Fairphone, as they offer a smartphone made from slave-free labour (Librem 5 isn't).
For me it is pointless to buy made in USA given NSA. I would be better off blending in crowd, or buying from within EU.
As for planned obsolescence, FP2 has 5+ years of support as we speak. Without help from Qualcomm, as they EOLed SD800/801 long ago. That's the same SOC as in the Mars helicopter, btw.
The point I made still stands: Librem 5 is made from slave labour (gold, cobalt). Especially sour with the 2000 USD price tag.
