A decade ago most people I knew thought of Elon neutral or even positively, he was just a figure that was doing good stuff with cars for the environment. At this point everyone I know thinks he's pathetic and a disgusting person.

I don't know when the Cybertruck was announced initially, I believe Elon had already started to enter the public eye a bit more aggressively... but sentiment has definitely changed over the last ~8-9 years.
