> Open Source is a proper subset of FOSS (Free and Open Source Software).

Other way around.

You all are confusing Free Software with FOSS.

FOSS is "Open Source" and "Free Software", where "and" means union, not intersection.

Obviously OSS cannot be a superset (more than) FOSS.

Huh, I always took it to mean intersection, but it does make more sense the other way around!
