It wouldn't be terribly surprising. Forking everything provides a liiiitle bit of protection against things like the 'left pad' incident.

Left pad was from the creator pulling the code from the public source forge, not from a destructive code change.

I assume all of the big tech companies host internal mirrors of every single code dependency + tooling. Otherwise they could not guarantee that they can build all of their code.
