You do see it happen. Dropbox was known to have a bro-y, male dominated engineering culture in 2013 and earlier, but since then has become significantly more diverse due to cultural changes. (To be fair though, it never suffered cloak-and-dagger problems described in Fowler's post, making it more plausible to alter the culture)
However this doesn't seem to have helped at Zenefits, and I guess it didn't help at Uber either.
Even more concerning is I would guess (and Linkedin corroborates this a bit) that the SRE org where this harassment occurred was basically lifted from the Google org tree.
And, oh, yeah - I had three managers in that six months. One was fired, one quit precisely at his one year, and the third had 70 direct reports.
If you see candidates coming from Uber, tenure past a year is a warning sign. I knew a few I'd want to work with again - A lot more I wouldn't.

From the claims, if you can go all the way up to the CTO and still not have a resolution then it's beyond hope at that point. They can't claim ignorance. In this case they valued performance > integrity.
