Climate Group Funded by Bill Gates Slashes Staff in Major Retreat

I am curious: I have read the article and don't believe his decision to be particularly bad and the reasons understandable.

While I agree that no one person should have too much power - Bill Gates at least tries to do some good with the money he accumulated. He is no angel, but there is a stark contrast to other billionaires who only use their money selfishly, try to earn even more, or - in Musk's case - to behave like a cartoon supervillain.

So why is he often viewed so negatively? Am I missing something here?
