What stops indies from using illegal software to build their games?

Problem with Blender is people who design user interface there are ‘hipsters’; they want to make sure every single standard is broken.
This is way so many find it hard to use, and it’s also why I hate that thing.
I hate that custom cross cursor so badly; just give me my computer’s default mouse cursor, no need for this fancy BS.
I end up just using Maya LT, to the hell with Blender.
