Nope. I think people are misunderstanding the difference between courts interpreting "putting something in the public domain" as a permissive license and actually severing the copyright from your legal person. There's no current provision for severing those rights under the current law so it may be possible for them (or their heirs) to claw a work back from the public domain using copyright termination/relicensing provisions of the law [1].
The way copyright termination works is a big risk to opensource either way because in theory any open source license could be revoked after enough decades.
