I don't think anyone is missing the point, and I think everyone understands disappointment. What some take objection to is the idea that Disney did something wrong, or they callously messed up plans, because Disney didn't. If you made an ADR, Disney is going to serve you breakfast. That's all they ever promised to do. If you made the ADR with the intent of having Main Street to yourself, or to get an early jump on crowds, then your plans are messed up, but you were making plans based on assumptions that Disney is under no obligation to honor. I agree you've suffered a perceived loss, but the loss wasn't ever yours to really have. It was an added benefit that was nice, but not part of the package. WDW could have just as easily taken you the back way to your ADR, or escorted you back to the RD line, and you still would have gotten what you paid for. So the continual refrain if WDW screwing people over gets tiresome, because it's not true.
As for people upset because the benefits of RD are diminished, I say the same thing. Disney never ever promises that folks at Rope Drop will be the first and only ones in the park. Frankly, I think RD is the reason for this new program. It used to be Rope Drop was a cute little ceremony for those folks who wanted to get up early and see it. A few hundred people, maybe a thousand in the heart of the season. But now lines often go back much farther as people have learned about all the benefits of getting there early. And now they've had to put cast members in place to manage the throngs of people who want to sprint as soon as the doors open. They don't want people to have to think the only way to get tow of the most coveted rides in the park is to have to camp out the night before and they don't want their park's opening to continually be a stampede. So if this diminishes the viability of Rope Drop for some -- hopefully many -- people, WDW couldn't be happier.
Both this and the Evening event's purpose, in my opinion, is to even out the traffic flow during the day. They don't want 52,000 people arriving at opening and leaving at closing because that's a logistical nightmare. What they want is a nice even flow of people, maybe 5-7 hours at a time, because that makes the crowds more manageable. So they are going to give some of their crowd an early start with the hopes they'll get burned out by 3 or 4 (or earlier) and then give people who want to come later a chance to shorten their day, but get on more rides later at night. The crowds aren't getting smaller, and there's no indication they ever will. So WDW is trying to figure out a way to reduce the impacts of those crowds.
