Scan of facebook/folly returns an incorrect Declared holder

A recent scan of
filename `folly-2022.06.27.00.tar.gz`
purl `pkg:github/facebook/folly@2022.06.27.00`
from
https://github.com/facebook/folly/archive/refs/tags/v2022.06.27.00.tar.gz

returns a Declared holder = `Google` rather than the more obvious Facebook or Meta. Very surprising. I took a look at the Project web site
https://github.com/facebook/folly
and noticed that it contains a reference to
https://groups.google.com/forum/?fromgroups#!forum/facebook-folly
so that provides a clue to the problem, since I don't see any reference to Google elsewhere.
Since Google groups are fairly popular, this is probably worth investigating as a pattern that is likely repeated in other projects.

Scan results attached.
