It's surprising that a closed source company can be so successful with open source developers. The reason is because it's free for open source projects. EDIT It's the same motivation as Oracle's recent "reverse engineering" drama, they don't want you to have the source. Will this end up true: those who sacrifice freedom for free deserve neither ? [BTW: Franklin's "essential liberty" was actually self-government requiring taxation - like github charging; "purchase a little temporary security" was gifted funds for defense of the frontier - like donatiomware (e.g. OpenSSL after heartbleed). https://www.lawfareblog.com/what-ben-franklin-really-said https://www.lawfareblog.com/what-ben-franklin-really-said ]
