Take a moment to think about this situation. If you take out the non-binary and racial aspects of the story, it basically sounds like a rant from a disgruntled employee.
On a related note, although I'm in IT which is completely different environment, contractors are outsiders. I've been on both sides of the desk so to speak, and it's rare that a contractor has as much pull as a full time employee.

The only one I know of is TherosOOC, any products in particular Orion worked on? Might be interested in taking a look.
I'll note that even if Orion's story accurately painted WotC as running "business as usual" or something approximating typical corporate culture, it's still bad and not the way that successful companies treat and develop talent. Especially not if they're actively trying to appeal to an ever younger and more diverse audience.
That something is common does not make it right, good, or even acceptable.
