Will once again re-up the concept of a “right to root access”, to prevent big corps from pulling this bs over and over again: https://medhir.com/blog/right-to-root-access
But if anything, regular people should have more of the cake.
The courts assumed good faith with a licensing exception, and maybe it was. But that opened the door to essentially completely dismantle the first-sale doctrine. Get rid of that loophole and all this stupidity ends, immediately. Well that and the DMCA. Once you buy something, it's yours to do whatever you want to do with it short of replicating it for commercial benefit.
As a more specific way to do this, I'd like to see any software that hardware companies make for their own hardware designated (at the choice of the company) as either part of the hardware or a separate product. In the former case, it must be made available under GPLv3 with full anti-tivoization provisions. In the latter case, it must use only public and documented interfaces and must be completely realistic for another company to make a competing product on a level playing field. Ideally the separate products would also need to be highly cross platform if technically feasible where the burden of showing that it isn't is on the developer.
