Canon and Nikon have always played copy cat.
Back when, Leica made rangefinders and was pretty much the big cheese in the camera business.
Nikon and Canon made knock-off Leicas for ages.
Then Pentax came around and instead of making knock-offs, they when with the novel idea of a 35mm SLR (quick-return) with a pentaprism viewfinder.
When Pentax started makin' it big, good ol' Canon and Nikon jumped the rangefinder ship and started playin' copy cat again by making SLRs.
Now with Sony making quite the splash with mirrorless, again Canon and Nikon abandon their customer base and force loyal customers to move into their new system.
Canon and Nikon don't care about their users - they care about their bottom line.
Unlike Pentax that states the will be a partner with their customer for life - they know their users love Pentax for a reason, and they aren't going to change that to chase market fads.
Pentax isn't chasin' the mirrorless mania just to appease some shareholder. They are staying true to themselves and what they stand for.
