While I do think the Autodesk software is expensive, and Blender is amazing for what you get for free. The majority of people consider the UI of Blender to be very poor, and I agree with that, when you compare how it does things to some of the more popular programs you wonder why Blender does them in such a way. Another thing, is that Maya includes many features that Blender doesn’t. Program performance is probably faster too. Vray is also a really excellent renderer, easier to use than some others like Mental Ray, and it’s been improving speed and features over the years and continues to be improved regularly.
It’s likely you are just used to Blender since that’s the first program you’ve used, people in general don’t like change. I wouldn’t consider the Maya to be something like “this is amazing! I need to spend thousands of dollars on this right now!” but you’d be much better off using Maya or 3ds Max if you want to work in the industry, at the very least you’d have difficulty working into a pipeline if you only know Blender. Or if you want to go with something cheaper try Modo which is becoming a good game development tool.
The reason you might be getting such negative reactions is because of the way you come off–many professionals that are very good at 3D would not say they’ve mastered something
If you’re having some trouble with getting answers to questions, some reasons could be that it might be an obscure problem that not many people know, or it could require a long response and people don’t want to have to take the time to write it all out. I know I see some really general questions like “how do I make a game?” and there’s just too much to be said.
