The parent post does make a decent job of pointing out that it's pretty rotten, from the top to the bottom.
The players at the bottom are terribly toxic, the C-levels are allegedly just as bad.
I am curious if this is more about culture - I would imagine EA and Niantic for example to have a relatively boring office, just normal cubes and meetings. Just engineers and designers going to work.
Riot and Blizzard both have large flagship franchises that they practically decorate their offices around, statues and all. When I was talking to recruiters in the past, Riot stood out as one of those "don't bother applying if you aren't absolutely shitting passion for our games out of every hole" as culture fit.
