Ask HN: Do companies donate to open source projects?

I know mine has. We weren't a big shop, but we donated to the OSS software companies that created the software we used. Each month, we took ~200 dollars and gave it to one of a long list of OSS companies, some of which include:

WordPress Foundation Bamboo Invoice Apache Foundation ~half a dozen really clutch guys who developed obscure but awesome plugins LibreOffice Flowplayer

Just to name a few.

A lot of the progress in LuaJIT has been sponsored. http://luajit.org/sponsors.html

Mine certainly has. We try to do at least a little something to the projects our business uses most. Tor, openvpn, openwrt etc in our case.
