Agreed.

Under GPLv2 the rights granted are to "copy, distribute and modify". Under v3 
they are, as near as I can tell, your "beloved" 'Four Freedoms'. See the 
difference? GPLv2 can be boiled down to mandating the "open exchange of 
software", GPLv3 does the same, but also attempts to force the philosophy of 
one group on everyone else.

First of all, because we want everyone to believe exactly the same things we 
believe.

I agree with attempting to protect people from the DMCA. The simple fact is 
that I feel that the GPLv3 would be better if all the "philosophy" crap was 
removed from it and the language cleaned up and simplified. In fact, add 
GPLv3dd4's section 3 was added to the GPLv2 it'd do just that.
