Cutting off one's nose to spite one's face. The more people use your software, the more feedback you will get, the better you will make your sofware, and the more opportunities for engagement you will have. Opportunities to engage to improve your software. Opportunities to engage to spread the message of open source. "This is free? What's the deal?" "Well, it's like this...." If you limit your software to those who are already on board, you do nothing to honour the spirit of the GPL, which is outreach and increasing freedom. (Full disclosure: I use Ubuntu for my server, OSX for my desktop; I used Ubuntu on my desktop from about 2005 to late 2013, until I got tired of GUI churn, of having to roll my own to get reasonable UX, and hating going back to my laptop after using my wife's or daughter's Air. I still use a fair amount of OSS, e.g., brew, LibreOffice, a few others, because these fill gaps the main OS doesn't address. Combining proprietary and OSS gives a better UX.)
