This was 2011-2013, everyone knew. Epstein was already convicted and served time in 2008-2009.
Melinda met Epstein once in 2013 and said that she "wanted to see who this man was". [1] Of course her spider-sense was tingling in the presence of a known predator. The meeting cemented things in her mind, and as a woman/wife she didn't understand why Bill continued to meet with him.
Bill of course had no problem with Epstein. Gates regularly put aside any sense of morals/ethics for his own selfish financial interests. There was money to be raised here.
Melinda's main problem with Bill was mainly his character, multiple affairs, etc. Combined with other things (like his decision to do business with Epstein), she eventually came to the conclusion she couldn't trust Bill any longer. Not surprising, given what we know about Bill's ruthlessness and general inability to stand by his word.
I'm all for Bill bashing, but there doesn't appear to be a smoking gun here, just a lot of clickbaity speculation. I'm open to any evidence to the contrary, but all I can find is that Bill met Epstein several times, flew on Epstein's plane once, and he never visited Epstein's private island.
I worry that Gates misdeeds are being diluted with time and good PR, and he'll simply be remembered as the guy that did a ton of good (with some unsubstantiated allegations of misbehavior, which of course all dog all powerful people), and not for the person he actually was.
As they say, history is written by the winners.
