It got me thinking--something similar happened to digital cameras where all the cheap point and shoots were replaced by phones so that now standalone cameras are an expensive niche for photographers.
OpenPOWER piggybacks off of IBM's high end POWER offerings, which are themselves part of a big enterprise market for scientific and financial computing. The OpenPOWER derivatives use IBM's POWER 8/9 chips.
I started looking for an alternative to commodity desktops when news came out that there were ring 0/-1/-2/-3 vulnerabilities in chips and I realized I had no idea what code was running on my computer. A lot of people just applied the mitigations and shrugged like it was perfectly normal that they couldn't really control their own computers.
When Raptor came out with their offerings, I thought it was great: full ownership of my computer, and as an added bonus some premium IBM chips from another architecture. I know people who spend more than I spent just on graphics cards every year.
