> What if a company change license, drop the project or goes bankrupt?

You can always fork the project, then the questions of sponsorships still remains.

Recently Ghostty is a non profit, which means that it is guaranteed not to turn into a for profit and rugpull like what MinIO has done.

That doesn't guarantee the devs stay motivated either.

In the end open source allows motivated people to take over the project if you aren't willing to do it yourself but projects can also die of lack of motivated/paid resources.
