Most Musk, Bezos, Zuckerberg equivalents were similarly divisive and controversial figures while they were alive or active (say, Ford). That only went away when the people who experienced them aged out.
Steve Jobs is a nice, more recent example, being just about old enough to remember his death, I know he was very much an asshole with many strongly held opinions most people would've disliked, but a current teenager is probably only aware that he was the visionary founder of Apple.
Bill Gates is also an interesting example, he was notorious for being cutthroat back in his day, but since he has mostly just been doing charity stuff since retirement, that reputation is fading.
