FLOSS needs commercial software

This is a post to be considerably fleshed out, but using Mac OS X has made me think a lot about the quality of FLOSS on different platforms. 

The quality of the commercial software on OS X seems to have a positive effect on the FLOSS available for the platform: If a developer wants their app to be used they have to make sure it is of a high standard.

The potential financial gain of innovating in an ecosystem where paying for software is considered normal also stimulates creative solutions and new ideas. There is an incentive to get your idea or technology out the door before someone else takes the market share. The same motivation does not seem to exist on Linux.
