A lot of people get angry when the money came from the gov’t (aka their taxes) without their permission to help someone who has more money than them.
Money is our economy’s way of rewarding those of us with outsized skills. It’s far from perfect, but it’s the best we’ve got. Is Tesla and Elon the best place to put that $465m? Maybe, maybe not. But it was the best we had at the time, and I certainly don’t see anyone better than him now.
But I don’t think even a majority of the populace had an issue with it anyway - it’s always the fringe extremists that get most of the press, they tend to be a lot more quotable than the ‘meh, I guess that’s fine’ folks.
