I think we know Gates had dinner with Epstein a few times, we don't know that he was involved with Epstein's wrongdoing or that he knew about it but of course we don't know that he wasn't or didn't. I think anybody involved with Epstein, however, demonstrated that they were bad judge of character and could have bad judgement in general.
I am not so offended by Bill Gates having affairs but I am offended with him having affairs with Microsoft employees.
