Everyone has their own frameworks for risk assessments, its more of the historical incidents associated with it than politics
But let's be real: Musk exists as a polarizing political character, and his association with Grok just breaks some people's brains. A fair number of those people don't want to admit it, and just latch on to any rationalization other than politics.
Anthropic could make the same mistake tomorrow, and I guarantee that we wouldn't be hearing about it in a week, let alone months from now.
On a personal level, everyone have their own rules, they may not be able to imposing them on others , however they do happen to evaluate their relative understanding of other people based upon those rules.
For me personally, I would probably put Anthropic, OpenAI and Grok in the same bucket, they are doing everything possible to make money. Ethics, morals, long term impacts, all of such things are not in their playbook. But again what these companies are doing just reflects the people who invested in them and what they want out of it. In some ways you can say its the money trying to maximize itself at all costs.
