I disagree. People who have wanted mirrorless cameras haven't been denied anything.
First, mirrorless cameras even up to A7R2 were pretty horrible. Those viewfinders, for my purposes, were just not usable, and there were too many other sacrifices that had to be made just to... well I'm not sure what.
And that's what it all comes down to. At the end of the day, I don't really care about whether my camera has a mirror or not. I want a photograph. Which tool is better to give me that photograph? The novelty of a EVF or all the other nifty gizmos wear out pretty quickly -- in the context of hundreds of photos of day -- and what I really want is something in my hands that gives me more pictures I'm happy with.
5, 10, or 25 years from now, will my camera have a mirror? I really don't care. Whatever solution is better overall as a system is the one that I'll choose. I'm not attached to a mirror, but I do like fast autofocus under conditions where less light hits the sensor; I do like an AF system where an illuminator will let me focus at good distances without consideration to ambient light; I do like a camera system that has a battery that will last through a day. And for the time being, even with the great EVFs today, I do prefer the actual optical image through the lens.
Certainly, 5 or 10 years ago, mirrorless cameras were not a great option for most types of photography; hence my comment that nothing has been denied from you. Technology in something you like just hadn't gotten there yet.
I am happy for you and other mirrorless shooters that you feel that you have more choice today. I think that's great that the choice is there fore you. I was simply commenting that there are far more mirrorless shooters that say "Death to mirrors!" than DSLR shooters who say, "death to mirrorless!".
Right now, for me, mirrorless is mostly a novelty with relatively few real benefits. But they are a fun novelty, and I've spent money on lots of stuff that I ultimately don't use much, so I will buy more mirrorless cameras. Until they "get there", however, I'll probably still reach for my DSLR for a lot of stuff.
I don't resist change -- I just don't embrace it without immediate, tangible benefits to me, and I'm not willing to buy several iterations of beta products to support an idea, hoping it will get to where I want it to be.
