The implication is that the OSS contributor has to be good. The same with street musicians.
I once had the pleasure of encountering some street musicians that were very, very good. I bought their CD out of their suitcase. It remains one my favorite CDs. Pludo's "The Only Thing Certain Is The Future".
Sadly, they never made it.
The large majority of street musicians are worthy of a tip, but I'll pass on their CD.
P.S. It's a lot easier to make money as programmer than a musician. You don't have to be anywhere near the top 0.01% to have a good career.
