Over the top? It rather sounds like a direct consequence of the first 
paragraph. You are basically threatening to take action if you feel 
something was "stolen"[*]. Without a clear definition of what that means 
(i.e., under which condition use of code from GNU Smalltalk is 
permissible in combination with Squeak) the only conclusion is that one 
must stay away from GNU Smalltalk as far as possible to avoid potential 
litigation. Which is more or less what Randal said initially.

[*] It always amuses me to find Squeak code verbatim in GST; good thing 
that we can't threaten action over "stolen" code, eh? ;-) Which, to me, 
completely settles the question what licenses *actually* encourage 
sharing and which ones don't.
