Blender is for models, not art. It’s different software. It’s great at what it does. Expecting that because one open source project can beat proprietary then all can is a pretty shallow view. A project relies on volunteers, sacrifice and funding.
You’re saying it’s bad because no one you know uses it doesn’t suggest no-one uses it, just you don’t know the users of it. Maybe your circle is as open minded to software as you are. Similar people surround themselves with each other. It says more about you than the software.
