If they lack money they could always scale back operations.
Also running the for-profit arm the way Altman did isn’t the only way.
A more reasonable CEO would do what he/she can to make money without running afoul of the charter. Yes, it will be less profit - and sometimes no profit at all - but that’s the way it should be in a non-profit organization.
OpenAI used to be an organization that dabbled with various AI technologies. Anyone remember their DOTA2 bot? Before Altman turned it into all about commercializing their LLM - going so far as to try to lobby congress to create laws, in the name of safety of course, to hobble any upstart competition.
So OpenAI should just shut down because the charitable donations were not enough to keep the lights on.
