Money, ideology, coercion, and ego.
But tech isn’t like that, there’s always a new startup and a new VC firm that don’t care that you ripped off every single previous person you worked with, stole trade secrets… maybe this time will be different
Or maybe word gets around locally or for special research positions.
All this is moot of course because I'm weird and don't have any desire to make money from things I don't consider ethical even if I knew for sure I could get away with it, but I can at least understand other people not feeling constrained in that way (or not finding this particular thing unethical, since from a lot of these threads it's clear that the idea of "trade secret" as something legally protected is not universally popular). This crime in particular just doesn't seem like a smart one to do even for people who don't mind the idea of making money from it.
And plus, their duty is to a higher cause! All humanity needs them to win, so that the superintelligence is “aligned” to their superior values… like “all’s fair in love and war”! (/s)
…rumblings of “divine mandate” in there somewhere…
