I kinda feel like big tech regrets that we got away with PCs running all foss software. The existence of GNU/Linux saved us in a way, I think some still try to lock us behind Windows I guess but Linux options are not going anywhere and they keep growing stronger I believe. However when it came to smartphones they tried so hard to keep them locked and far from what a natural computer would offer (running anything as long as your CPU architecture supports it). While Android phones got some freedom in the past I believe they’re getting more closed and harder to tweak. Also I was there when iOS jailbreak peaked with all the crazy stuff (it was still hard to switch OS though). Fast forward to smart watches, now these are far more locked than phones and very limited in terms of freedom (even tho some run standars CPUs architectures). I think no way would big tech allow glasses to have freedom and they would make them close to what watches offer these days, maybe worse. I really believe that we should be able to run whatever the hell we want on hardware as long as it is technically possible.

Tl; dr: GNU/Linux saved the PC industry, corpos will not let that happen again with another industry.
