alternatives ?

For procedural texturing darksim n substance designer only two I can think of. texture maker uses procedural but it's a different kind of app. darksim n texture maker are all but ghost.substance designer ...

You would think there'd be a lot more procedural texturing app's.

For 2D painting textures.There's a lot of choices. Photoshop & zBrush.probably some of the best current choices for making 2D textures. I don't have in my home studio but 3DCoat or Mari there descent choices also.

substance live would be killer if there EULA allows it . & I can learn substance designer.I swear it has the highest learning curve I've ever seen in CGI.
