If we can't get models not to say racist or otherwise terrible things, we can't make any guarantees about our ability to control or guide some future AGI.
A very much secondary reason I appreciate these (admittedly annoying) attempts to control LLM output is that I do think it is responsible to consider the societal impact of accelerated and automated hate speech and propaganda. Telling large AI companies not to consider these impacts and just release the raw models seems akin to being grateful that Facebook et al. never stopped to consider the societal impact of social media, when we all know that it's had significant negative side effects.
