No it's not that. People just go against their own interests to support things or people they are familiar with. Remember when they put C Log in the 5D IV. Do you not think that was the result of people asking for it or complain about the lack of it.
You are a little too defensive to get the point. C log is an example of people acting noticing something important was missing and they spoke up which is what we should do as a consumer. Otherwise a brand would have no incentive to innovate or add features, just because because you believe you personally dont need it as if your needs reflects the entire photographic community. Your Sony example is terrible. that could just be boiled down to a few reasons from material costs to just not being able to do a good touch screen but i bet they will fix it if more people would complain (if it really is a problem i have little experience with sony cameras). It's not like Sony is saying " We will give them a crappy screen so they can buy an a9, but not make it that great so they can buy an fs7, but not make the FS7 too good so they have to buy an FS5 as well." That's how I feel about Canon's way of selling products. I forgot to add, the against interests part is about defending such a practice and not demanding the most.So people bought the 5DIV without C-Log against their best interests? I bought it but without C-Lo even after C-Log was introduced - I don't do video so did I buy it against my own interests?
People buy the Sony even though they have a really poor touch-screen function. Ar they buying against their own interests, or do they just have different priorities?
People know in full what features a camera has and to tell them they are buying the wrong thing is really patronising.
