Also by contributing to gedit (probably for free), you help this guy
selling gedit on Mac:
https://www.macupdate.com/app/mac/57936/gedit
If you read this, please don't buy gedit there, there is a free (but
older) version here:
http://ftp.gnome.org/pub/GNOME/binaries/mac/gedit/
Well, looks like selling a newer version is something that's entirely
marketable, then.Maybe contribute to gedit and try to sell an even newer version for Mac? Selling free software isn't a bad thing to do.
