I don't mean to imply that 1 review on glassdoor is the smoking gun. But a bunch of reviews talking about the same issues (not specific to sexual harassment), and other comments and testimonials not on glassdoor seem to point in the same general direction. Proof beyond a reasonable doubt doesn't mean it needs to be incontrovertible.
Let's not miss the forest for the trees here, this isn't about a single case of sexual harassment (at least to me it isn't). It's about how Uber is operating as a business and culture and from that what are its long term prospects.
Healthy Skepticism is well... healthy, but I think at this point there is enough evidence out there to confirm the story.
Case in point, a quick look at glassdoor reviews seems to confirm the story. (there's even one that says it's "Not Great for Women" - Sep 2016 although it's not as devastating as this article but the info from that and other reviews seem to support what she's saying)
It's disturbing when it seems people are jumping react before all the facts are there, but it seems the story is verifiably true. If there is still doubt, I think the discussion is better served by bringing up specific items than a whole cloth rejection of the story.
Even if I take your assertion seriously, he should have been warned to stop at the first accusation. Literally all he needed to do at that point was to not try to date within the company, even the most clueless guy figures that out after a formal warning. If not, I question his basic reasoning skills.
This isn't a case where it was the first accusation nor was it where he or other people in management were unaware (the issue was escalated), the behavior was inappropriate.
The problem is the management was told there was an issue, repeatedly, with evidence, by several people, and choose to not act upon it. Doesn't matter if it's sexual harassment or incompetence, employees won't tolerate bad cultures if they can help it.
This is a lot of things, sexual harassment, work culture, accountability, office politics, etc., but some guy being clueless about women isn't one of them.
