Did Microsoft have a reputation for sexual harassment and toxic managers? I don't know much about Microsoft in the 90s.
Their reputation was more around 3E's (Embrace, Extend, Extinguish), they didn't play well with others (intentionally).
The key thing to remember is most people at uber and microsoft are decent people.
That doesn't stop the 2010s to 1990s comparison, relatively speaking, from also being true.
