That's exactly what I'm saying -- I assumed user C is a new user,
registered after the recent change, and B an old user.  So by
uploading any change, user C confirms that they hold the copyright to
the work and transfer all rights to OSMF.  But it's obvious they don't
because they just downloaded the previous version from OSM (usually),
and they may be in violation of the sharealike in CC-By-SA (assuming
CC-By-SA was valid for data).

That means that newly registered users as of two days ago can't make
any edits other than those exceptional edits where a new version is a
total remake of the object, not deriving from the previous versions.
Especially they can't undelete things, under the contributor terms
they agreed to.
