>FOSS is typically created by individuals, not by corporations (although there is a shift toward FOSS companies), and since the software is free, you can not sell or license it to make money.
Most major FOSS projects have significant corporate backing--and have for a long time. And those companies sell open source or otherwise use it in ways that make them money.
I think there are plenty of examples out there, but they're all enterprisey, not consumer-targeting. Consumers tend not to have sufficient requirements to make it worth purchasing support and licensed versions of anything bigger than Sublime Text. Businesses love this stuff, though, since open source allows them to fix things in-house and send patches upstream rather than having to wait for the vendor to get to it.
