People seem to forget how many companies Bill Gates put out of business by using their designs. It takes years to sue and win damages minus lawyer fees. Then to try to whitewash his reputation by giving the money away.
If Bill Gates was merely using his vast wealth to whitewash his image, after a career as a ruthless businessman, that's understandable (though not agreeable) because that's what billionaires (who became so, by being ruthless and competitive) tend to do.
But Bill Gates has been using his vast wealth as a weapon and Think Tank for Big Pharma - he is actively using his wealth and clout (under guise of charity) to harm and kill poor people and innocent children (by doing experiments on them with unproven/dubious drugs as "clinical trials") without their consent.
Now that is pure evil.
I think it's the opposite. People remember how Bill Gates got rich. They remember that the damage he caused mostly affected capitalists and professionals in developed countries. His businesses mostly didn't abuse labor in developing countries. He didn't cause that much environmental damage. He didn't undermine democracy and the society that much.
People remember that Bill Gates played the game and won, and the damage he caused was mostly limited to the economic sphere and to other people playing the same game. That's why they are willing to give Gates a chance to redeem himself by using his money for good.
