I haven't yet seen the evidence that it's unsustainable. People are still doing it. It seems to be working. There's no reason to believe people are going to stop doing it or that it's going to stop working.

It might be important to you to get paid for your work. Okay, charge for your work then! That was always allowed. There are many people who are okay with doing certain work for free. Maybe they just want to put it on their resume, or they already have enough money, or they just really like that work. Open source is working fine.
