Yes, it's such an important issue for the left that it's extremely easy for an opponent of the left to have someone say something vague about some prominent progressive figure and instantly discredit them forever, because people will usually just go with it, and there may well be residue suspicion even if they are at least partially vindicated. I think here it is different because there were multiple reports of people quitting his campaign, although it didn't seem to be about sexual assault or anything like that, just "usual" mistreatment of staff.
