More precisely, man-hours that can be directed by leadership at a specific goal. FOSS is great at creating things that programmers want, like text editors, terminals, and web frameworks, because programmers will do those things for themselves. It's pretty bad at creating things that non-programmers want, like WYSIWYG text editors, spreadsheets, desktops, and web browsers, because programmers will only do those things for money, and there isn't enough money in FOSS.

For all its other faults, Apple got this right with Mac OS X: Apple pays people to write a coherent desktop system, but it's still Unix under the hood for people who use and develop FOSS. Android and Google Play have sort of done this for phones. I think there is a market for someone to make a paid, non-FOSS desktop based on Linux, since there are plenty of coders who don't want to hack on hairy desktop stuff.
