Maxon just like Autodesk (mudbox and sculpting beta inside Maya) conceded defeat of specific feature sets to outside devs like Substance Painter, Mari, Zbrush and 3D Coat who had better performance and a growing user base. Blender is the only developer actively pushing sculpting and texture painting in its app and from what I've seen many pros people still prefer Zbrush and Painter. The difference is, Blender isn't beholden to shareholders or worried about trying to turn a profit so it can keep developing toolsets that people may not even use, like their editor.
