BitMover's closed-source product, BitKeeper, was used for source control for the #Linux kernel. Larry McVoy, CEO of BitMover, was upset because someone tried to figure out how BitKeeper worked and McVoy pulled the BitKeeper licenses from Linux developers.

Needing distributed source control, Linus Torvalds created #git in a couple of months.

BitMover is gone and BitKeeper is now open-source, gathering dust.
