It may be clear to you, but it is not clear to several others, including
me.  Multiple people have pointed out the obvious case of Tivo, if they
had a Linux kernel patch, would they have cause to object if the kernel
went from GPL v2 to GPL v3?  They contributed expecting to be able to
benefit from future improvements made by others, and now they can't
benefit.

Similarly for many embedded devices, the length of the GPL v2 is already
an issue.  The GPL v3 is much longer.  If I am a maker of embedded
devices and have a copyright contribution, do I have the right to object
to the extra space and/or paper that is required to convey the longer
license?

As a practical matter, very few open source projects have properly
registered copyrights to deal with.  And so it may be hard to quantify
and prove actual damages.  But there are real drawbacks for some
contributers to moving to the GPL v3.  Whether or not they would win the
legal case, the objections are real, and I am glad most project leaders
pay attention to them.

Suppose that I think a licensing change benefits 95% of my contributers,
but is bad for 5%.  Is it OK to make that licensing change?  I submit
that it is not, because I have no right to coerce that 5% to give of
their freely given labor what they didn't choose to give.

YMMV, and lots of people's do.  But in this case, I think the legal
system agrees with me.  One litigious person with a real beef can
generate a real lawsuit that I can lose.  (Not to mention the lesser but
important issues of generating negative feelings and publicity.)

Ethics is only simple as long as people agree on what is moral.  When
they don't, it becomes very complicated, very fast.  (Particularly when,
as is normal, the disagreeing parties don't recognize the source of the
differences.)
