No I don't blame them either for wanting to make money, good luck to them, but personally I think they're way too over the top and greedy in their obsessive dictator attempts at control, but as an owner of a used device you are free as a consumer and legal owner to do with the device as you wish, obviously as long as you don't steal SCT's IP (intellectual property). If by past events you're referring to the falling out between SCT and CAPA re the old X1, but what if CAPA had at the time no reliance on say SCT's software and CAPA could control devices themselves, I wonder if the outcome would have been different as to the ludicrous restrictions SCT brought about... I mean SCT's clamp down on X1 support and the 90 day (from memory, or was it 30?) time limit to get your X1 to a dealer... to me that whole saga proved SCT's ludicrous conditions.... also what about when SCT tried to enforce ON THEIR OWN DEALERS for god's sake, all the new conditions about Advatage III, that anything a dealers creates with ADVIII is SCT's legal property and SCT for any reason can revoke a dealer license at any time and cut-them off (as ADVIII insists on an internet connection to function) and a dealer has to hand over all copies of anything created and destroy any copies and this contract between SCT and dealers has to be physically signed and sent by snail-mail to SCT etc etc and it was only after the so-predictablke outcry by dealers that SCT withheld all this stuff (withheld mind, not removed... at the tiume) ... SCT as a company just seems to come up with some crazy stuff...
Oh and re your point, you can return a car to stock parts first and then return to stock tune, but realistically, most users of these devices that's not really an option many times I would haver thought, so I think my initial point about a device being, in many cases, a one-time use sort of thing...
