All these things are used by nerds and have little chance of breaking into the mainstream. They're too labor intensive to use and deploy and impose too much cognitive load. 10% of the work is making it work. The user experience necessary for mass adoption is the other 90%, and it's mostly work that is not fun and that people must therefore be paid to do. If the goal is just to have a for-nerds-by-nerds ecosystem that's fine, though ultimately I think without mass market penetration it's likely that the hardware ecosystem will eventually close. We are seeing the encroachment of locked boot loaders everywhere. Eventually it may be hard to get a fast modern chip that can run the open stuff if the open stuff does not have sufficient mass in the economy to demand it. That and I for one think privacy and freedom for everyone is a worthy goal. For-nerds-by-nerds is elitist.
