Yes, I have seen this article. however, I found out that your forum no longer receives feedback on mixamo and mixamo will not be developed. This upset me. Please tell your admins that the lack of mixamo development is upsetting the Game Developers.
I understand your dissappointment but this user-to-user community has no influence over what Adobe does. The fate of a product is determined by corporate-level decision makers.
Ending a product is never an easy choice. They probably have good reasons for it. Perhaps the technology is not extensible enough for further development. Or they decided not to compete with 3D tools like Adobe Substance 3D. In any case, this isn't the first time Adobe have ended a product and it certainly won't be the last time.
Other product forums like Photoshop & Lightroomhave dedicated forum sub-spaces for posting bugs and feature requests. So it really depends on which product(s) you use.
