Why is Fuse no longer available?

Fuse can still be used. https://drive.google.com/drive/folders/1OnrDtH8lyBroPD5hgtTMahaaQHaq7qrQ

the Fuse on steam is the older 1.3 build before Adobe stepped in and it is currently still there and still free

while this build is older than what Adobe posted the models are the same but the actual textures have a more cartoon look to them... with some skill it is possible to swap models between the two builds and we did have tutorials but they are gone now

as a heads up this older 1.3 build os for Windows 7 and Steam is about to drop all support for that OS which means in the very near future even this build will be gone

you have fuse on steam for free

I was really bummed when Fuse was discontinued. It was a robust little program that saved me a lot of time. The mixamo library doesn't offer the customizability Fuse did. I'm hoping Adobe adds a similar character-building product in the (near) future.

Fuse was made by Mixamo and Adobe wanted Mixamo for the staff... mostly because they had 3D software that works on Mac

Apple Mac dropped all 32bit software which blocked Fuse from working well and promted the end of life call... yes Adobe said the program would keep working after end of life and yes that was a lie because anyone that allowed Creative cloud to update after the end of life will find Fuse no longer opens so to answer your first question, Adobe killed Fuse by mistake

if you still need Fuse your best option now is to grab the free 1.3 build from Stream and use that but if you are happy to pay $ then Iclone will take all the Fuse models \ assets and convert them into modern tools

AA_lique33, I am very sorry, but Adobe Fuse has reached its end of life.  This can be frustrating when you get accustomed to using a particular application to complete a function.  Would you please bookmark https://helpx.adobe.com/beta/fuse/faq.html, which provides information on Adobe-related alternatives.
