there are specs and there are other specs. Some materialize in every image captured, some don't ever. some i don't care for (eg "4k" or any form of video capture), others i do care for quite a bit:
stills image quality, AF performance, responsiveness, straightforwardness of user interface, reliability, pricing ...
some specs are "paper relevant only", many others count in real life and with every single capture.
While Sony does not lead in all "specs dimensions", Canon has allowed them to do so in some and get darn close in many others. Canon (and Nikon) sat pretty much helplessly like lane ducks, iterated their mirrorslappers, made half-assed attempts at mirrorless (Nikon 1 anybody?) and let Sony become a true and formidable challenger on the way to take #2 spot in the stills imaging market. Had Canon acted just a bit more proactively it would not have happened.
Sony's foray into stills imaging gear could have ended with their ill-devised and deservedly ill-fated SLT/A-mount series of "mirrored bricks". All it would have taken from Canon would have been a "halfway decent", compact mirroless FF system 5 years ago when Sony launched the original A7 triplet (A7/R/S). Sony would have been dead in their tracks from day 1. Now Canon (and even more so Nikon) face a much bigger challenge to come up with an (overall) really winning mirrorless FF system. Not impossible by any means, but much harder than 5 years ago.
Same for APS-C systems: Fuji would not have gotten a leg on the ground, had Canon launched their APS-C mirrorless system with an EOS M50 as a start - specs and features. plus two more EF-M lenses. But no, Canon "held back on specs" and tried to charge outlandish prices for their underspecced 1st gen EOS M. as a result they had to give it away in a big firesale and Fuji has successfully established a small foothold in the market. Almost all Fuji mirrorless sales could easily have been Canon sales. Almost all Sony A7/A9 sales could easily have been Canon sales.
no amount of "smoke and mirrorslapping" can hide the serious mistakes Canon and Nikon management made. no speculation needed, looking at the facts is sufficient to understand the picture. Canon's relative success in a shrinkibg market is mostly "inert mass still in motion" - large customer base, strong brand name - like a large oil tanker, it won't stop on a dime. but it can run aground quicker than Sony may decide to end selling stills image gear.
