They should team up with other projects like Ubuntu Touch, SailfishOS, GrapheneOS, PostMarketOS, etc, at least for the base OS and device drivers. This would mean a lot more hardware available, and some pressure on manufacturers to be compatible. One project I’m really interested on is the Liberux Nexx.

I know this is a bit too hopeful, but if we don’t get at least some of the general public on our side and put pressure on manufacturers then it really won’t happen.
