Ok let's take for example the guys at FabFilter. I bought their plugins expressly because they were offering them as both AAXx64 and VSTx64.
How about PSP Audioware? That's why I bought Xenon.
Waves? Yes, I have S-1 and De-Esser running as x64 AAX.
An anecdote about a guy who can't afford a license fee so he can sell stuff, is just another type of anecdote. For all we know that guy that says he can't afford the license fee has all his money tied up in real estate in Maui as a labor of love.
In the case of Voxengo the proprietor says he can't get Pro Tools to work so he can't test his own plug ins in it.
Voxengo is slowly drifting in to past. For example, their premiere reverb, a really fine reverb, which I own and formally used as a go-to, is still stuck in x86, and it seems as if there is no intention of updating it.
Voxengo keeps sending me emails about their latest updates etc. but nothing they are doing is as important to me as learning that I can use their stuff on either/or DAW I am using at any given time.
I'd buy Pristine Space and Elephant all over again at full price in AAX, but apparently it is too hard for Aleksy to figure out how to get Pro Tools to run on his CPU.
