Canon, way back with the AE-1 cemented their camera design pholosophy, and it was so successful that they have kept to it.
Basically, they concentrate on value. They design and redesign a camera, pricing and justifying each decision and always looking for better and cheaper overall design, construction, and maintainability solutions. They balance things out, so each is optimized for value.
This means that the product will likely not incorporate the latest and most expensive technology unless it actually contributes to the value proposition. Is a UHS II card reader / writer necessary if UHS I does all thats needed. Is 4K worth the additional cost based on the target market? Are dual card slots necessary if the target buyer only owns one card? Every decision is scrutinized with the goal of getting the cost down and producing something reliable, easy to build and repair, and has a maximized profit.
There are always tradeoffs like these no matter who the manufacturer is, but Canon seems to be a extreme example. The result is that the product is well balanced, has good performance for the price, is reliable, and repairs are faster and cost less. And, important to Canon, they make a fat margin of profit. Canon and other manufacturers all know that Canon can undercut your price, so they don't try to beat Canon on price.
With several decent manufacturers producing some very interesting designs, there are cameras with the features you want most. There is no camera that has everything you want, I don't think its possible because we all value different things. So pick what works for you.
Remember Beta Tapes versus VHS? From a high tech point of view, Beta produced a better recording. But, the recording time was initially one hour, not long enough to record a typical 1.5 or 2 hour movie, and VHS was two hours. By the time Beta was extended to 2 hours, VHS was at 6 hours, and VHS had won. The very best tech quality was not valued as much as recording time by the general public, and VHS recorders cost less. (BTW, my first VCR was a Sony betamax, I still have two or three.)
That same general lesson still applies, know your market and what most customers want. Low price is number one as long as the product is good enough, is reliable, and service is good, but there can be one item, like recording time that trumps it all.
