Canon has nearly 50% market share, more than Sony, Nikon and Fuji combined. Who do you think is the 800-lb gorilla in the analogy? The tail doesn't wag the dog. It's Sony and Nikon who are targeting the smaller market segments that Canon is ignoring.
Sony led the MILC market for a while. They entered that market because they couldn't compete with Canon and Nikon in the DSLR space. Sony shifted their focus to full frame MILCs the same year that Canon launched the EOS M line. If you think that's coincidence, there's a nice bridge in New York you might like to purchase. The M line went on to become the best selling MILC line, at its peak about 17% of all ILCs sold globally were M cameras. In 2018, when Canon launched their first FF MILC, DSLRs still outsold MILCs. That only reversed after Canon fully committed to mirrorless. Another coincidence? Perhaps you're prefer some prime Kansas swampland to that New York bridge. I expect Sony will keep making high MP cameras, as will Nikon...and both will be glad that Canon doesn't. Until they do. The question you should be asking is where Sony will go next. Remember the Vaio?
