Trying not to be salty, just giving my objective feedback regarding the topic:
For me the main selling point of Allegorithmic's software was the flexible business model itself. Personally, I use substance only occasionally as I keep most of my work in Houdini. That being said, there is absolutely no way I'm paying a monthly subscription for something I don't use on a daily basis, no matter the price. Yes, I'm aware licensing won't change for now, but we all know adobe, hence the reserved "for now" part. From the very start, the main selling point was the ability the buy perpetual licenses and have that software lying around until I needed it and if I liked new updates enough, I was willing to pay for the upgrade. And I had faith you were going to deliver those worthy updates (and you did so far, so thanks for that). Part of which was because you needed those worthy updates to keep selling your product. Forgive my skepticism, but with subscription only based business model (led by no one else but adobe), I kinda doubt those worthy updates will be happening.
I've been able to dodge adobe so far and unfortunately, I won't jump aboard this train with you. Now my only wish is to keep my perpetuals for the software version I payed for, adobe not being able to scam me into their subscription down the road and repress the sad memory of all of this happening. Allegorithmic not being corporate is what gave me confidence in it's future, this software package just lost all it's appeal to me. Hope it was a fine sum, as many hearts were broken for it.
You were to bring balance to the force, not leave it in darkness
