Thanks for the question, it is very valid.
You are right, the XMPP server ecosystem is very diverse (in terms of
implementation language). Yet, most of the implementations are GPL'ed.

I prefer BSD/ASL-licensed software - not neccessarily as a user, but
when writing code. (The GPL is a very good and a strong license, and so
are BSD-type licenses. Every class has its weaknesses and strengths. I
have not the slightest interest in discussion superiority of any of
them.) It's intended providing a choice here for XMPP server users.
Implementation-wise we are still far away from being that choice.

You could still argue that I should have tried to persuaed some
implementation to move to ASL, but (if they'd had agreed) that would
have taken all the fun of writing a XMPP server from scratch.

Thanks! :-)
