Git replaces BitKeeper (2005)
BitKeeper, the kernel's proprietary version control system, revoked its free license amid a community dispute. Torvalds built Git in weeks rather than accept the limits of the tools available.
Git became the kernel's version control and later the industry standard.
It established Torvalds' willingness to reject tooling restrictions and build his own path.
A prior case where Torvalds ignored externally imposed constraints on developer tools rather than work within them.
