I think maybe you missed a piece of the puzzle:
To date the World Food Programme hasn't received any donation from Elon.
It wasn't about solving World Hunger, it was about helping countries that are in famine... which is a huge problem in places like Afghanistan right now.
I don't care about Elon buying Twitter, he can do whatever he wants... I personally think it will be good for Hive if he actually does... but liberals weren't losing their minds over him not spending his own money on solving world hunger, more that he didn't do what he said he'd do.... with his own money.
