I wouldn't even be so upset if it wasn't for just how complicated the new blackout dates were. It's not even about the money, it's about being able to understand how my old pass is blacked out Spring Break, Summer, and Xmas week, to now, scattered blackout dates every single month, including most Saturdays, for the new equivalent version.
Paying for a confusing product that looks like it was written by an algorithm to maximize profits doesn't sit well for me, much more than the cost.
Obviously, as mentioned above, the nonsensical names don't help.
But also I think the changes you specifically mention are WDW trying to adjust to central Florida going from a backwater to (close to if not already) one of the largest 20 metro areas in the country. Twenty years ago, Saturdays were slow--it was a "travel day" for out-of-state vacationers, and not enough locals to have an effect on crowds. Reems Road and SW Davenport were all trees, not subdivisions. Now there's enough local APs that it can swamp the park. We're not L.A. yet, but I think there's a realization we're creeping up, population-wise.
ETA:
I’m paying $900 for the option of 365 days at WDW, when I go to renew next June if I purchase the equivalent to what I have now that would be the Incredi-Pass (ugh with these new names too) which would be $1,399, had to add the extra $99 to include Photo Pass which already comes with Platinum. Oof.
At this point I should be thanking Disney for pushing me to invest in the bucket list trips I’ve been wanting to take instead.
I'm with you, it's a hell of a price hike at the top level, but they're trying to get us to just give up Thanksgiving and Christmas. At the "1A" level (I refuse to use the names), that's the only blackout dates, and with renewal personally saves me hundreds over the 365 pass.
But ultimately they need fewer people in line on busy days. Short of massive capital expenditures--Disney Decade level stuff plus--this is the way they do that. For every AP who bails, it makes the guests left in the park more likely to be in a good mood and spend more.
