since it seems it has been forgotten, remember the reason Git was created is that Larry McVoy, who ran BitMover, which had been donating proprietary software licenses for BitKeeper to core kernel devs, got increasingly shirty at people working on tools to make BK interoperate with Free tools, culminating in Tridge showing in an LCA talk that you could telnet to the BK server and it would just spew out the whole history as SCCS files.

Larry shortly told everyone he wasn't going to keep giving BK away for free, so Linus went off for a weekend and wrote a crappy "content manager" called git, on top of which perhaps he thought someone might write a proper VC system.

and here we are.

a side note was someone hacking the BitKeeper-CVS "mirror" (linear-ish approximation of the BK DAG) with probably the cleverest backdoor I'll ever see: https://blog.citp.princeton.edu/2013/10/09/the-linux-backdoo...

see if you can spot the small edit that made this a backdoor:

if ((options == (__WCLONE|__WALL)) && (current->uid = 0)) retval = -EINVAL;
