Sure, but how do you (practically) prevent a work, on which no one
reclaim ownership, from being used and not "shared-alike" ?

Any restriction comes only from a person having legitimate authority on
the work (the author).

If the author disclaim ownership, how, and why could he restrict uses of
such a work ?
