And, for a person I know who complains about screencaps, this is the transcript:

but remember the GPL was designed to defend your freedom
and the conversation you're actually having is
how much freedom can we take away, please tell us!
and we say "you are not allowed to take away any freedom"
but can we take away a little bit of freedom?
well you have to ask a lawyer
why should we have to ask a lawyer how much freedom we can take away?
you should tell us how much we can oppress you
don't fall in that trap
