Notice the common factor here - MT/Commodore was making a lot of
"working but only barely" chips and Commodore used them internally to
save money and also sold them to others which used them because, well,
they were frequently the cheapest.

Radio Shack TRS-80 would buy every Z80 that did not make 2MHz
operating frequency. They used something around 1.87 MHz so the
CPU clock and the TV clock were the same clock.
RaptorCS buys POWER 9 chips where a higher number of cores failed
than permitted by IBM's specs, and then sells them as systems with
a lower working number of cores.
The main disadvantages are a) price and b) they are stuck with POWER
9 (due to the binary driver blob on Power 10, among other things).
