So Larry was into BDSM, that basically made women slaves. He was into the whole community thing and went to a wedding that was in the community. He gave a speech. he shared his speech. Larry's enemy used that as a weapon.
But Larry's girlfriend was/is mentally challenged - I dunno what exactly but there were some issues on the mental side of things that she needed help with. (Not meant to be nasty, I dunno how else to put it in a better way) Larry said he talked to the therapist/doctor/whatever who looked after his girlfriend and explained their kink to make sure they were ok with it and she wasn't being taken advantage of. This was a big deal to the people who didn't like Larry and they kept banging on about how he was taking advantage of a vulnerable woman.
Larry took her to a drupal conference thing. She wrote some code that went to Drupal's code base and those commits were attributed to Larry. There was an implication that she was forced and enslaved to write code for Drupal.
Larry's enemy as far as I know actually broke the code of conduct and I believe was banned.
Larry as far as I know while didn't do anything against the code of conduct was stopped from being allowed to contribute to conferences and various other things and basically stripped of his position within the Drupal Community and he was reasonably well respected within the PHP and Drupal community however he wasn't banned like the other person and remained in the community. He is still active there with his last post being 2 days ago.
