Since he didn't get copyright assignments, each contributor is the
copyright holder of her/his own contribution.  And this means each
holder gets a say on how s/he understood GPLv2.

IANAL, but I think if Linus' intended interpretation had been
clarified all the way from the beginning, he could have grounds to
claim that everyone else had implicitly accepted that reading by
contributing to the project.

But since it was a decision made many years later, his clarification
on his reading of the license is in a way an additional permission
that affects only his own contributions; other authors are still
entitled to try to enforce their understanding of the legal terms of
the license, and they would have the spirit of the GPL and its
preamble on their side to guide the interpretation.  Even if contract
law states something like, in adhesion contracts, the party who writes
the contract gives the other party the benefits of any ambiguity in
the writing, the GPL is not a contract, it's a license, and per
copyright law, licenses are to be interpreted restrictively.

In the sense that he can decide to remove all contributions from
dissenting authors, yes, he does.  But he can't impose his more lax
interpretation upon other authors.  Under copyright, it's the more
restrictive reading that prevails, in that any holder who understands
his rights are being trampled can enforce them.  And since at least
one such author is vocal in his dissent, not even estoppel defenses
would apply.  But IANAL.
