That's called CYA. They all left one-by-one yet seem to be on "good terms" with each other (how to survive in the industry when needing references).
That's how and why that woman committed suicide. She knew she couldn't go anywhere in the industry without those devs and management references.
WHY women haven't spoken up as the doors close if they do, not that the allegations aren't true.
The more lawsuits come out, the more they can't operate like before. Women know work environments and all the junk that goes on within them. They can relate even if they're not video game devs.
