I mean he just tweets about bitcoin so often. He may be thinking that he is guiding his followers out of bitcoin but what he could be doing is making them more curious that they will eventually buy like his son did.
Pretty much an average old guy that dislike the fact that bitcoin is destroying his gold stack. As much as I hate to admit this but bitcoin is not going to be popular with all those 'old guy' that has impact on financial / economy to some degree. They are going to be sticking with either gold or property, their safe haven for years
Bad publicity is still publicity eh?
Depending on who tweeted it. It could give a bad impact though. Warren Buffet's statement regarding bitcoin / crypto gave a bad impact iirc
