While I'm happy to believe any/all of that might be true, accepting unsubstantiated stories like this isn't a great idea. You really need to start with the assumption that all stories like this are fake until some kind of evidence is provided.

If I was going to do some kind of exposé of my employers I'd at least include some semi-obfuscated screenshots to add some credibility to any claims I might make. Sure, things like that can be faked but it at least would require more effort to do all that (and make them appear credible) vs just a bunch of raw claims.

(I also don't think it's a great idea to judge claims based on how believable you personally find them. That often just leads to confirmation bias as you're just reinforcing your own biases).
