From a game theory perspective, Sundar's approach is actually probably the safest approach. If they didn't add the "over the top" diversity and inclusion filter, Gemini would probably not be given a second chance if the twitter-verse was able to generate anything remotely objectionable as presently the diversity and inclusion crowd has somewhat captured social media, etc. and is quite vocal and experienced w.r.t. canceling people/companies/things.
If Google adds the diversity and inclusion filters and the social media influencers/stock market want it to be less filtered, then Gemini gets to live another day. The Gemini team can go in retro-actively and remove the diversity and inclusion filters and Sundar can write an apology letter.
Then if the Gemini team goes too far in the opposite direction, there is precedence to apologize again as they fine tune it.
