Take a look at the project in question. It's a fairly straightforward github action. I imagine facebook has some (probably quite sensible) policy that they shouldn't rely on random third-party actions, and rather than just forking it they thought they'd build it to better suit their needs.

Launching a new product using the extremely unique name of an existing open source project this is not.
