I don't think Trump invented this playbook if that is what you're saying - the power hungry have done this forever, but we can now just see it all in real time.
What made Trump different, and what these other leaders are following, is that he chose to put it out in the open. It wasn't something that just happened with changing tech, he did it on purpose.
With a leader like Steve Jobs you got a lot of rumors about callous behavior in private but got a polished exterior. Trump upended that when he became popular by being publicly crass.
