What is the exact scenario you're against? If GPL changes are added to a BSD codebase, it's still possible to use the BSD part of the code under the terms of that license. The GPL doesn't "infect" the rest of the work, either in the present or historically. You aren't "forced" to re-distribute the source code unless you want to use the GPL changes - which is just how copyright works in the first place.

They'd only own the copyright on the minor change so can't force everyone to use GPL on all of the code.

This occurs very rarely and provokes a loud counter reaction from the BSD people.

It seems such bsd people then don't believe in the power granted by the bsd license to others using it as they wish to. Ironically. May I suggest GPL for their next project?

Whining is not illegal, if you can whine about a license change, you should.

But by the very act of making their code bsd, they have removed any valid excuse to whine. Anything that happens is just a natural consequence of their decision: whether that be someone making bank on your code without giving you any of the changes back or GPL projects GPLifying a fork of you.
