Why is the C50 NOT more popular?

The C50 is an amazing camera.
It doesn't have IBIS.
I never use IBIS.
I recently watched a couple of R6V reviews where they called the C50 a "Niche" camera.
But now folks are looking forward to the R6V.
I like the price but I want cinema menus and audio top handle.

But Original question, is the C50 a flop? Is it Niche?
I think it should be more mainstream
