While it is absolutely right to insist on the original license, I find it also a bit surprising they rather have their contribution removed than allowing a more liberal license.

To you it's more liberal, to others more exploitative.

People get really upset about license changes, as Linus so nicely observed.

As I said, I fully agree that people have the right to deny the request.

Maybe they considered that if enough people said no, then the relicensing would be cancelled.

That is probably correct and within their rights to say no.
