This is a matter of politics; it's a matter of reputation.
I'm fine with using AI tools offered by companies like OpenAI, Anthropic, and Google despite knowing that these companies are ran by billionaires who are much more aligned, politically, to Musk than they are with me.
What I'm not fine with is handing over valuable data to a guy that has literally completely captured the US government and has shown a disdain for being perceived as someone who even pretends to follow social norms or respect societal rules. You can just look at his actions with regard to Twitter and you can see, without needing any political lense, that he's openly haphazard about this kind of technology and how he wants to use it, especially for his own personal gain, because he knows he's untouchable.
The guy just sucks at the job of being the face of these companies, and this is how sucking at that job affects the bottom-line. But, again, that doesn't matter to him because he has so much money that he can just personally bankroll past those inadequacies.
