In Redmaus's defense, he was very generous when I contacted him to let him know he had a couple of proprietary keyboards for a system of mine. I picked up two TI Professional Computers, and handed one off to someone else from CR who had been looking for one. However, the keyboards were nowhere to be found. I later found out that redmaus had picked them up. He mentioned he was planning to remove the switches, as they were a rare type and the keyboard basically looks like a generic 80's PC keyboard. However, when I contacted him and asked him to spare the keyboards if I offered to buy them for a decent price he held off scrapping them. Once I explained they were proprietary and the computer was useless without them, he ended up just giving them to me even though I offered to pay for them.
He's not a bad guy, he just got carried away at CR. When you see literal piles of the very thing you collect for dirt cheap, you tend to grab a bunch of them. I'm not saying I agree with everything he did, but he did at least apologize and actively attempted to rehome the proprietary boards he picked up to people with those systems once he realized they could not be replaced.
I can't speak for all the deskthority people, but I would bet most of them just don't realize that a bunch of those keyboards are special, and the machines they go with are bricked when they are separated.
