You are just saying the same thing you've already said before.
It really isn't even a phenomenon, being active in a handful of watch forums tells me the date is very important to plenty. In a day and age of smartphones that has practically made watches irrelevant, many just use the watch for quick glances at times and dates. But it doesn't change the fact that I don't like it as an update on remade classics and I feel it ruins it.
So yeah I will blame Longines for such a decision to ruin a classic in exchange for sales.
