The bashing of equalization as a tool is ignorance but the use of equalization as a solution is ignorance too ... Equalization is a useful tool not an acoustic solution ...It help alleviate some problem but do not solve any acoustic problem by itself alone ...
I use EQ after establishing the right equalisation levels with my modified headphone because so good they are , they are not perfect, no headphone is , and can be too far at some spot from the Harman curve and my ears ask for such slight improvement ... It could be the same thing in a room for a form of DSP , the best DSP is the BACCH filters , eveybody needs this one knowing it or not because this DSP is an acoustic solution with no trade-off ...
