Also means that a robust community of people creating businesses to sell variations of the hardware for those who aren’t as maker friendly cannot emerge, correct?

Bc imo that’s what really got early 3d printing off the ground. Like back in 2010 during the reprap days there were all the independent maker storefronts plus a few bigger ones like lulzbot and makerbot (that eventually all got put out of business or bought for toxic modern shit like bambulab because in the modern day under capitalism every single industry has to consolidate until it’s under a few large extremely consumer hostile companies with okay products that just eventually get worse and worse bc there’s no competition or regulation for them but I digress).

Without this industry or a proper open source platform I don’t see how this will succeed
