I would bet it's more he cares way less about tesla now that the hard stuff is done and the huge factories are designed and spitting out vehicles. He's moved on to spacex and that brain implant place, where there's still plenty of really hard engineering going on. I don't think it's fair to say any era of Elon would be ashamed of taking money from people either. he's always like money and has had no problem shipping crap as the v1 of something, to be improved later.
