Are you just expressing cynicism or are you actually interested? If the latter, you can just talk to insiders.
I had a somewhat curious personal experience at Uber. I went to interview there circa 2016/2017 and got an offer but had to wait for a visa to come out. In the meantime, the Susan Fowler scandal exploded. The hiring manager reached out to me out of his own accord to express his own outrage and how he'd absolutely not tolerate toxic behavior within his area of reach, and that many others within the company shared that feeling.
Turns out he was right: the team I eventually joined was fantastic and indeed there was a very large part of the company that was deeply troubled (and often quite vocal!) about the growing accounts of harassment and injustices. Driven by pressure to get the house in order, this eventually culminated in hundreds of separate investigations, and various degrees of corrective actions (including firing several perpetrators)
Since then, I've heard my share of complaints about higher ups as well (being in a role that involves quite a bit of cross-department communication), so it's not like it's all rainbows and roses, but my main point is that if you ask the average joe in a company, they're often happy to be straightforward with you.
