They are not mutually exclusive.
All of these companies rely increasingly on low-paid, contract work. In the interests of cutting cost, they let veteran designers walk and bring in people fresh out of game design school or whatever who barely know their ass from their mouth. In the case of Bioware, they purposefully fucked over Andromeda. I've yet to see an example of a game ruined by the SJW boogeyman.
I don't think it's just the direct impact people mean when talking about the "SJW Boogeyman", but mostly the pressure they try to put on these companies via social media, which sometimes is amplified by the media trying to get those outrage clicks out of it, don't get me wrong, its still the company fault for succumbing to this sort of shit, most of those people don't even really give a shit about diversity, racism, sexism, or whatever, they just want to see others bending the knee yo them, it gives them an illusion of power.
Bioware sacrificed a lot of their artistic freedom just to appease to those groups, when the sad reality is that many of them never played and never even will play their fucking games.
