Dear Bruce Perens:

I didn't get into this in my previous letter to this list, because it  
wasn't perfectly germane to the point of that letter, but I want you  
to know that I get it.  I understand that you correctly understand  
the effects of the TGPPL, and that in your opinion those effects are  
not valuable, or that their value is less than the costs of having  
another open source licence on the list of open source licences, or  
than the costs of having open source software published under  
mutually incompatible licences.

It may come as a surprise, but even though you and I disagree about  
the relative value of the TGPPL, I actually respect your opinion and  
the opinions of the other members of this list on such topics, and I  
know that other people do, too.  When such people come to you and ask  
"Would it be a good idea to release my software under the TGPPL?", it  
would be perfectly appropriate for you to advise them against.   
However, when people come to you and ask "Is the TGPPL an open source  
licence?" it would be inappropriate for you to reply to them "Never  
heard of it.".

Regards,

Zooko
