No, it's based on the paragraph which you oh-so-convinently deleted.

Don't play bullshit games.

Doesn't matter.

You said that a restriction is free if it protects free software more
than it hinders it. Therefore any license is free if it is in some way
sufficiently useful to free software, regardless of what restrictions
it introduces. You have introduced the notion that restrictions can be
excused.

This is a feature of both licenses together. You cannot claim that the
GPL is somehow responsible, for example:

...the SSLeay license, part of OpenSSL, which has a clause that was
written for the explicit purpose of hindering combination with GPLed
works.

There is nothing in the GPL that you can point to and say "This clause
hinders free software".

Furthermore, this is not a significant restriction. It is trivial to
release your free software under a GPL-compatible license, and this is
not appreciably burdensome. The occasions where it doesn't happen can
invariably be traced to laziness or political obstructionism.

I'm pretty sure that we'd include a clause to explicitly prohibit it.
