Good points. Viewing it from the lens of the original business model or mission, it's a disaster.

I don't think it's right, but I can see how a billionaire just completely overrides the company mission and business model after they buy enough shares or something.

Maybe there are other non-obvious use-cases for other companies, where you're effectively buying the user base to then pull the rug.

A lot of the original customers will just accept such a change. See Twitter or GitHub.
