OpenAI is a brand, not a literal description of the company!
If the brand name is deeply contradictory to the business practices of the company, people will start making nasty puns and jokes, which can lead to serious reputation damages for the respective company.
A very vocal minority can often have quite some influence on the majority. See for example the Wikipedia article on "Minority influence":
OpenAI pivoted from non-profit to for-profit and it's fine to criticize them for that, if that's the argument you're making. But focusing on their name specifically doesn't make sense. I mean, what do you expect, that they rebrand to something else and lose a ton of brand recognition in the process? You can't possibly expect a company do that when they have no incentive to.
