I've said it elsewhere, I'll repeat it here..
What I don’t get is how you can abandon your brand.. Building a brand like Allegorithmic did was a HUGE achievement.. Sure it’s very likely the tools will improve, but the brand equity’s gone, that’s a big big loss.
I come from advertising. Building a brand isn’t only about name recognition, it’s how your customers feel about you, what they identify you with. In the comments I see a lot of “I thought you guys were different”. People worry about pricing and Linux, but it’s not why they’re reacting that strongly IMO, they feel let down. It proves you were able to create an incredible emotional bond with your customers, it's something that other companies spend millions trying to achieve, and now it's out the window... And it's not about liking the usage, or the amount of features.. I love using After Effects, I despise Adobe. Why does it matter? The day there's a decent alternative, I'm gone (that program is the only reason i still use CC BTW).
Substance is a fantastic product. Most of us will keep using it I suspect, and I do believe it will improve, but even with the same name, you’re now Adobe, and that sucks.
