Got to be realistic. That was one piece of software and it took decades and a team and plenty of free labor to get to where it is. People have to eat daily.
FLOSS devs do eat daily. It's not developed by fasting people.
The vast majority of FLOSS projects are underfunded and we have far more cases of projects that had to shutdown because they lacked funding than projects that were successfully able to fund themselves.
Survivor bias backed examples are not a good argument.
