Finally someone who tries to present an actual reason for avoiding SBI! The difficulty in trying to get someone to clear this very low bar is not a good sign.
To start with we have some tweets from @legobutts from 2016. The tweets are bad, I will not try to defend them. Deleting them was the right call, you say something stupid or bad or should delete it. I have no idea where in the SBI hierarchy @legobutts works, but he appears to be a consultant, not an employee. I suppose the argument is SBI should not have them as a consultant, but should SBI be searching the internet archives for everything someone has ever said in the past before working with them?
I will note: The tweets are from 2016, SBI was founded in 2018, so they were not working with SBI at the time. I will also note that @legobutts worked on Tunic, Untitled Goose Game, and Firewatch. I do not see any of those games mentioned on the SBI detected group, so whatever the curator's issue is with SBI it is not this person's past tweets.
Then, we have the reaction from SBI to the SBI detected group. Yes, their reaction is bad and was full Streisand effect. However their reaction to SBI detected is not the reason SBI detected was created in the first place, so we can strike that reason as well.
Moving on he didn't like some of the things said at GDC, but the clips don't seem problematic to me. They never said they were trying to eliminate all "white male" characters from games, and she gave a story about a cast full of white people and got push-back when suggesting making one a POC. I don't see the problem with that story.
So the reason's the YT leaves us with for people not liking SBI is because of DEI and bad writing. Bad writing doesn't require a curated list. Reviews will tell you if the writing is bad.
This leaves us with, surprise surprise, DEI being the reason. Anyone boycotting a company because of DEI is a bigot. Even if you think DEI is pointless and wasteful, then the company is wasting money on it. Companies waste money on stupid shit all the time. To be so opposed to the idea of DEI to boycott companies speaks volumes about the type of person they are.
