and
postmarketOS, and ... there are so many of these projects, yet they all share the same challenge: supported devices are very limited - you can't install it on *your* device (unless you happen to have a (old) device which is supported laying around).
Think about the business model for "consumer devices" - what are these companies making money on? Well, they sell you a new phone every two or three years! So if everybody keeps their phone for five or ten years, these companies will not survive.
So, the suggestion of the OP is "make money by competing and providing support services.". Let's look at it: who makes money by competing? Professional athletes and teams, nobody else. (Of course there is a broadcasting industry that makes money from broadcasting rights and selling advertising, but that is something else).
That leaves us with companies who makes money from "providing support services". Let's see, the big one is Red Hat and there are several smaller ones in different countries around the world doing the same thing as Red Hat on a local scale, this seems to be a working business model so far. But these companies provide *software* support, not hardware support.
Anyone who knows about a company that makes money from (open source) *hardware* support services, raise your hand.
And remember the key point of a
consumer device: it has to have a low enough price that lots of people will buy it...
