I use one, but then, I also have a realtime spectrum analyzer so I can actually see what the EQ is doing. And anyone using "tone controls" is still using an EQ, it's just broader in the frequencies it affects. I use one because, believe it or not, I don't think every yahoo who sits down in the mixing booth, or masters a record, is an absolute genius just by virtue of being the one sitting there. I can play a few instruments myself, and I've done some amateur recording and mastering. Plus, nobody has any idea exactly what the people in booth were going for, or what equipment they were working with. Not every studio is Abbey Road. On the other hand, my ears are absolutely not the same as the people in the booth, the artists, the guy who wants things to sound good in a car or on a portable BT speaker, the other guy who handles the compression for streaming, etc. So what they might enjoy, or even be able to hear, is probably not the same as what gets through to my brain. Hence, I like being able to tailor the sound to what I like, and that is in no way, to me, some sort of sin. I've actually heard that intentionally "distorting" the "artists vision" is akin to rewriting a beloved book. Well, some people can believe that if they want, but I don't.
