I'm not sure I'm justifying it... I think it's bad form to alienate guests, especially long term. I'm trying to understand what they're doing, though.
I'd say that Disney has managed to spread the load across the calendar. As many people point out, there's not really a low season anymore as far as attendance goes.
I would guess that even though you and others may not do things with your magic bands to even maintain an MDE account (is that even possible nowadays?) there is probably enough data, statistically, from those who do for them to want to use that data to maximize profits.
I agree wholeheartedly with your views and sentiments, by the way. My favorite Disney Decade was the 1990's... mostly the best of everything. It was less before and has been less since, though I was a fan of FP+.
I guess, to me, understanding what they're doing and why is the first step in trying to figure out a way to change it or circumvent it... or just realize that Disney's no longer a place I want to be.
