Getting upset that USAID spent the government equivalent of pocket change on programs that nominally helped other countries and practically bound them to US soft power is (1) cutting off your nose to spite your face and (2) not equivalent to deleting data that money was already spent on.
At face value I agree with everything USAID stands for, but it sounds like you have some examples in mind you want to provide.
Good luck getting any responses that have been corroborated outside of Musk's ramblings. So much for 'transparency'.
If someone was truly looking to audit places to save money, it's always been odd to me that USAID was first. Now this story comes out...
