You appear to be labouring under the severe misapprehension that FOSS is written entirely or even mostly by hobbyists. It's not. Most of it is written by people on the payroll of companies that make their money from it; either by selling support for Free software (e.g. Redhat, Novell, Canonical), or by selling hardware to run it on (Intel, AMD, Dell, HP, IBM, Nokia etc.).

Free software is all about freedom, and that's all it's about - it is not, and never has been about 'no-one gets paid'. If you want paid support for free software from someone who relies on it for a living, that's no problem, you can get exactly that. Indeed, one of the benefits of free software is that you can get that paid support from a variety of vendors, so you're not locked in to whoever supplied the software in the first place. With proprietary software, if you don't like the support you're getting, or you don't like the price, or the supplier drops the product, you're screwed. With freedom, you have options.
