Before just throwing a random list of projects here, let's say your budget is a $100 / mo (just a random round figure), what OSS projects would you now sponsor? That'd make you think about what you really want to see in the tech world.
My list begins with Firefox, Ubuntu & linux. I want to see OS, desktops and browsers not being solely controlled by for-profit corps.
In the same line, mobile OSes don't have a good alternative. Any suggestions?
