No one is saying the SPF community wants to _ban_ forwarding.  At least, 
I've not heard anyone say that.

Rather, they want to extort^H^H^Hract money for the ability to outsource
or separate parts of the mail system. They can also mess with the service
level of the other provider in ways that aren't easily detectable by the
user.

The blowback issue is different from this.  Blowback happens whenever
anyone _rejects_ emails based on SPF.  A bounce is generated from the
relay to the forged sender.  This enables abusers to arrange 100% blowback
as the abuse vector.

So, SPF rejection can't be allowed.
