There are limits to how much you can give researchers a pass though. There are plenty of senior researchers who have perfectly secure careers but want a bigger grant, more postdocs, a more prestigious position, etc etc, and of course they hold disproportionate clout with the funding agencies.

But as altruistic as they might want to feel, it's still ego, greed, or at best nepotism when they fight regulation which is for the good of the field.
