Put that way I totally see your point.
I've had Super Suite for a bit under a year, so I'm looking at it from a slightly different angle.
Just a thought... Best way forward for WA would be to move over to an annual licence. ie A licence which permits you to install 3, 6, 12, or all extensions in a 12 month period, via an all-in-one installer. This would provide a recurring income that would better sustain their business and thus they could continue to develop the extensions in the future
