As much as I don't like them, you have to consider the target demographic of the Pokemon series in the first place. I feel this is mostly something that older fans would have to bite the bullet and deal with for the most part, regardless of how annoying it is. After all, some kid might just be getting into Pokemon for the first time by the time S/M release; we can't make assumptions that every kid has been in the Pokemon series for years, as Gamefreak, as a business, would profit not just by keeping older fans interested, but attracting newer ones, as well.
That being said though, I'd still love for the tutorials to be optional, but I think in that case everyone (including the people that really don't know) would skip them and it would be a waste of time adding in the tutorial feature anyway.
