Making fabrication accessible would definitely be nice. In the meanwhile, I'd be interested in finding a community that puts "relatively open" hardware to good use. That includes old computers that won't grow antifeatures on their own, but also e.g. microcontrollers. I believe the dual-core 125MHz $1 Raspberry RP2040 is more powerful than my first PC was (although it might have less RAM and unfortunately can't be transparently expanded as far as I know). It's not exactly open hardware but it's well documented, and even the boot rom is open source (that is rare). You don't exactly have lots of integrated peripherals (e.g. ethernet) so it'd be very difficult for them to have some kind of remote backdoor. It's also quite simple to program; a hacker scale operating system is entirely feasible. And that is of course just one of many choices out there. There are far more powerful microcontrollers out there. And by their nature, it's not going to be very easy for the copyright mafia to get their slimy tentacles between you and the core. You'd give up a lot of power but on the other hand, I could buy 500 of them for the price of my laptop. I don't know, maybe we don't need to run everything on a single high performance CPU and could instead have a small cluster; perhaps each chip running its own application? It's definitely not a "ready world" but I see lots of possibilities and am excited for the future of microcontrollers. But I'm also seeing the line between microcontrollers and processors getting blurred.
