it's not that OpenAI is reponsible, but those board members have burned a lot of bridges with investors with this behaviour. the investor world is not big so self-serving interest would dictate that you at least take their interest in consideration before acting especially with something like waiting 1 hour before press release. No Board would want them now because they are posined apple for the investors.
Alternately, there may be mission-minded investors and philanthropists who were uncomfortable with Microsoft's sweetheart deals and feel more comfortable after the non-profit board asserted itself and booted the mission-defying VC.
We won't know for a while, especially since the details of the internal dispute and the soundness of the allegations against Altman are still vague. Whether investors/donors-at-large are more or less comfortable now than they were before is up in the air.
That said, startups and commercial partners that wanted to build on recent OpenAI, LLC products are right to grow skittish. Signs are strong that the remaining board won't support them the way Altman's org would have.
