My point is there's apparently a big market here, but it's also new. You didn't have Compaq, Gateway, Dell, Asus, HP, Vaio, Lenovo, Fujitsu, Samsung, Beelink, AOOSTAR, etc. competing in the PC clone market in 1993 yet either. Give it maybe more than a year to develop.
If it's important, I can't see why today's (and tomorrow's) computer vendors wouldn't move into the market. If it's not important, then it's not.
The NAS market is probably small because for most consumers, a single SSD already suffices. But even with that, you can already apparently buy from vendors that sell vanilla TrueNAS preloaded. Just like you can buy OpenWRT routers. Or even open Linux-based retro gaming handhelds designed to mimic a Gameboy Advanced SP. And soon GrapheneOS phones. I assume your employer buys from someone else?
