It's better that it's not funded out of generosity.

Now the OS projects can have two revenue streams: one funded by generosity, one by self-interest.

Motivation can be important. After Mozilla started taking Google's money they lost a lot of urgency about competing with Chrome to offer a different view of the internet.

In this case there don't seem to be any concerning dynamics and generosity or lack thereof is irrelevant. It'll be good for FreeBSD.

How could Firefox as a company afford to compete with Chrome or do anything without any revenue? Unfortunately Google's money is almost the only reason why Firefox is still a thing...
