Unless new things are trivial simple the average brain doesn't want to deal with the learning curve. Those who are willing to put in the effort, benefit, while others are content to not know what they are missing and it'll always be that way. I experienced this with my 1DX2 purchase - I read and re-read and practised and experimented, especially with the focus options. When I presented some of this to good old Artie he was unwilling to consider any of it, not even just back button focus. Why should I care if others don't want to take advantage ... I'll share with those who want to improve and keep quiet with those who don't.
