> By that logic open source software should be mostly crap...
And it is. Most free software projects never go anywhere. Those that do commonly have UI/UX that is far inferior to most consumer software produced for people willing to pay for it. The extreme right tail of open source software is great and most people who work on it are paid to do so. If you want reliability and quality paying for it works a lot better than hoping for people to do so uncompensated.
