If your services are not wanted, what business will still keep providing them?
Uh, the services are clearly wanted by customers.  You're right that the middle finger thing was extreme hyperbole on my part, and I apologize to everyone for it.  I'm just frustrated over having another generation forced upon us (support for Genesis 2 WILL be dropped, leaving customers with no new G2 products), and the break of tradition with Poser support which I find offensive, and all of this to sell-out by abandoning their indie small-business roots and hobbyist fans for the big industry/mainstream.  That, and I had a HORRIBLE day yesterday (that's not even counting how upset I was about the whole Gen3 thing)  Neither of which is an excuse for my behavior.

Who would provide services to customers that have been openly hostile to them, and don't buy their products?
I see plenty of customers who AREN'T hostile, and doing what they can to make Genesis 2 work in Poser.  Hell, we have a vendor here who makes Poser-only dynamic clothing for Genesis 2, and those outfits have texture support from IIRC at least two vendors.  I have also seen people complain about the scarcity of new(er) products in the DAZ store with Poser mat support.  This is a perfectly understandable grievance, IMO, and the incidents that I can recall folks complaining about it, it did sound as though they were interested in buying DAZ's products.

And while we're on the subject, there are 3D modelers/gamedevs/programmers of the big professional software who look down upon those who do not make their own models, and esp. look down on anyone who wants to use or convert a commercial product for even private use in Max, Maya, etc.  Purchasing a game dev license to use someone's commercial project rather than making your own is heavily frowned upon in some circles.  (This elitism is in many ways similar to the elitism you see among a subset of Linux, BSD, and Ubuntu users towards Windows and Mac users)

I think the previous point of statistics should be made here. Poser support was dropped due to the low percentage of users using the import technology. Redoing the importer for the new weight mapping and manipulation of all the new bones and facial wasn't worth the effort and wouldn't return on the investment. The api on SM's side hasn't not been improved for better performance while new features were added to the DS side. Doing things for sentimental reasons unfortunately doesn't work in business, though those affected may seem like they are being betrayed. Business are in business to make money, and recoup investments. In this case it was a better use of investment to switch weight mapping and targeting getting Genesis in multiple applications with industry standards rather than target one platform that wasn't making money and performance wasn't the best.  And the effort to make DAZ's products more compatible allows people from other apps to use them, but also it allows DAZ users to put Genesis in other apps as well, rather than just sending a static obj. There are DAZ users that ultimately render or have workflows in other apps as well and switching to standards allows them to use genesis with those tools and be able to pose them or not have UVs overlapping like in previous generations. This is a win for DS users as well. Also SM may be more apt to adopt the standards as well since they were apprehensive about using DAZ tech in their programs. Instead of a DSON importer that emulates, the result may be an FBX import that allows the genesis rig to be native and use Poser's tools, which were previously problematic with the importer. But this time, SM will have to do the work instead of DAZ spending resources to do it. DAZ has spent 5 years of resources with little return, so it makes sense to end it.
