A long history? Another search tells me that apart from the mentioned accusation, there is only one WSJ article alleging sexual conduct with SpaceX employees.
You asked why I take Musk‘s side in these discussions; it’s because I don’t think he’s a pedophile.
Nothing I‘ve seen seemed convincing to me, and the arguments made online often were so laughably inaccurate and exaggerated as to border on blatant slander.
