There are only a small number of cool/interesting ways to be not mainstream. Not X is not 'a thing' though it's 'not a thing'. Find your own blend of uniqueness based on positive motivations rather than bland 'anti'. I also really disliked how Go was billed as 'not Java' and in some ways is now catching up. Or maybe a better example is 'alternative' music, I liked kinds of it rather than the mainstream. Then it became the 'alternative' genre in itself. If you like grunge, etc you can use those rather than defining it based on the opposite of something.
