That's a really interesting article, and some very worrying stats.
From my own anecdotal experiences, there seems some truth in those observations, not just in academia but in many female dominated groups.
I started noticing the gender stuff years ago when plenty of women's groups on Facebook were throwing out members for criticising or questioning stuff. And the women admin would post a loooong list of rules of how we all had to be nice, kind, sensitive to hurt feelings, support any and every cause and underdog etc.
Women dominated professions like HR, are very big on pushing all kinds of initiatives under the D&I banner, and are more likely to do the whole pronouns in emails thing.
The men who do like scolding only scold women. They don't tend to do it to other men - mostly because many men will just ignore them.
So you get women policing other women and men who get a kick from policing women.
There does seem to be an inclination that when there's a conflict between being brutally honest about something or 'being kind' or nice, then women on average prefer to not rock the boat and smooth things over to keep the peace, even if it might be detrimental in the long run. I've seen this with men being allowed into women's online groups even when it makes other women feel uncomfortable.
There is a pragmatism in this mindset, given that men can and do respond very aggressively in retaliation.
Social interactions can also be different between women and men. Men tend to take the piss out of each other, lots of off colour and offensive jokes, rude banter - some of it seems unnecessarily cruel but maybe it does build a tolerance to feeling offended or upset. Women tend not to make jokes like that with each other or might chide others for being mean.
I suspect lots of factors feed into these issues, but I don't think you can have large swings in demographics and sex ratios without some (unintended) effects.
