Planet uses COTs last I checked. Most CubeSat companies do (at least that I'm aware of).
I wouldn't say completely ignored though. You still want to use ECC memory when possible and have redundancy. The ignoring that I'm talking about is rad hardware. Or rather sapphire chips. Those run up costs quickly and you're forced to use technology that's on par with silicon from 10 years ago.
