Which is why we should support him even more: https://news.ycombinator.com/item?id=22299156
If the former, having the movement spearheaded by someone who has pretty controversial views on the latter isn't really doing the movement any good. If FSF clings stubbornly to a thought-leader who people can't take seriously, they're canceling themselves.
I've seen the accusation leveraged in this topic that this anonymous piece could be FUD by Microsoft or a similar big-name software giant. I'd actually suggest the opposite: if I wanted to throw sand in the gears of free software, keeping Stallman in the leadership chair so that his opponents can point to him and say "You really want to listen to the guy who wants to sleep with your teenage daughter?" is the way I'd discredit the movement.
Who are you talking about? This is completely misleading and not what Stallman was saying.
There are more charitable interpretations, but "Stallman wants to sleep with your teenage daughter" is the less-charitable one that political opponents can continue to levy against the entire movement because the FSF won't let him go.
Stallman, even without the stuff mentioned here, was already a pretty poor choice for messenger. His tendency to focus on semantic nitpicking gave his arguments a kind of tedious quality to them (GNU/Linux, anyone?). The outspoken political views can turn off people who are not politically aligned. And he's always given off this sort of skeevy vibe to me personally--and that sentiment has seemed to be shared by lots of other people. Long before any of the stuff being complained about here happened!
The negative influence of Stallman isn't purely theoretical anymore. We now have a couple of stories of people saying that he made them personally uncomfortable with unwanted seemingly sexual advances. Apparently, these have continued after being explicitly told by several people to knock it off. Several organizations have suspended their funding and involvement with the FSF over his reinstatement. Whatever you think of the accuracy of the accusations against him, the general perception of him is clearly negative, and to be frank, it doesn't seem like he brings any positive qualities that would make letting him go be a tough call (consider Elon Musk, who is obviously a pretty effective salesman for the future and props up Tesla's share price even as his outspoken political views are causing real problems for his companies).
