He continued: “I give a lot more money to climate change than Elon, or anyone else. I give lots of philanthropic dollars. I back companies. Electric cars are about 16% of emissions. We need to solve that other 84%.”
Gates added: “He's done a great job, but somebody shorting the stock doesn't slow him down or hurt him in any way."
Musk replied on Twitter, too, simply writing the word “sigh”.
It comes after Musk accused Microsoft co-founder Bill Gates of shorting Tesla earlier this year.

The Tesla CEO admitted that he asked Gates if he was short-selling shares of the electric carmaker. When investors short a stock, they are betting that the price of the asset will fall.
“I heard from multiple people at TED that Gates still had half billion short against Tesla, which is why I asked him, so it’s not exactly top secret,” Musk said in the tweet.
He was responding to a Twitter user’s question on whether a screengrab of a supposed text conversation between the two billionaires was real.
The Tesla chief’s response was: “Yeah, but I didn’t leak it to NYT. They must have got it through friends of friends.”
