zstd can't really be attributed to Facebook. Yann Collet started work on it before joining Facebook, so it was kind of imported.

I am sure it made developing and standardizing the algorithm easier, but what makes it such a good (performant) algorithm is the design of the original creator.

On the other hand, the patent licensing kerfuffle (which I don't think was about any existing patents, just "standard policy") through the relicensing by Facebook was a drag on zstd's momentum.
