Re: poor quality of FOSS?
I don't think that there's any objective evidence that open-source applications are of any poorer quality than the proprietary ones they replace. In my experience with Windows, for instance, I've been forced to use a lot of really terrible applications that someone actually paid money for. And the Linux kernel itself demonstrates the excellent quality of software that can be produced by non-corporate FOSS developers.
But don't get me started on documentation! I'm not sure why the online help provided with Windows and Mac applications is regarded as a benchmark for quality. It's almost invariably terrible, too shallow to explain anything more than the basic functionality of the menus. You nearly always have to Google to find out how to do something unusual or complicated in Word, for instance. Compare that to the exhaustive documentation, tips, examples, and configuration information provided with a cross-platform FOSS application like Lyx. Or the Linux kernel documentation. Yes, FOSS documentation is very inconsistent (the documentation for LibreOffice is as bad as MS Office), but IMO its average depth and completeness is as good as commodity commercial products.
