This is true and has been true for everything non-Intel forever. I really thought open source operating systems would be a game changer for MIPS, Alpha, PowerPC, and others but it was a challenge getting hardware just to port stuff to. Literally, it took heroic efforts within those companies just get hardware to like a Linus or something. It's a little different with some of the raspberry pi like platforms on arm but you have some work to do if you want a specific late model processor. Sort of seems like an opportunity of Someone to build arm atx and miniitx like hardware but I don't know anybody doing it. It's all custom application specific stuff anyways...
