Although I share your point, I don't think I need to explain that not everyone wants to use EQ. You need additional circuitry(s) to do that and even with high-end devices like the expensive AVR-s for example, there are measurable degradations to the sound if EQ is engaged. This is just for example, but many other reasons are possible.
I guess but basic EQ to ear(not automatic room EQ) is cheap and easy to come by. I would assume anyone looking at Revel speakers can use it if they want. After all, it's free in most source software and even some source hardware and there's lots of hardware EQs under $100 too. The bar is not high.
