Not necessarily a recent cut - I'd say it's more likely that one arm of the company has no clue what the other is doing.
Yes. And this is typical of Disney for at least the past 10-15 years as it has become so large in size, scale and employment.
This type of decision was made -- at the latest -- during spring and, quite possibly, well before that. Of course, they (like any company that is so concerned with image) aren't going to 'announce' it to the public. They truly hope that few folks notice and fewer complain.
And that's the situation whenever they do something that really affects the guest experience in a negative way.
Or they simply turn it around and issue a non-sensical statement like the 'Tweet' from this Thomas Smith.
I certainly agree that I wouldn't focus your disgust with him. Again, a decision like this would have come from the level of a Dan Cockerell and/or an Erin Wallace. It possibly could have also come from Francois Lerioux since he is responsible for entertainment, but I doubt it was his final call (especially after his disaster with the new Stitch MK show that didn't last a month and cost millions).
But Smith is the voice of 'Social Media' for Disney, so you better believe that his Twitter account is there for that purpose. Still, I'd go to the decision-makers ... and I'd do so by phone (switchboard, NOT DRC), email (the addys are out there or easy to figure out, this isn't Bob Iger) and/or snail mail. Walking up to Guest Relations at EPCOT and berating some poor CM, who likely agrees with you and has no decision-making power, ain't the route to travel here.
I'd also make sure to NOT stick to just the LoW issue. Indicate ALL the things that WDW has done to tick you off (all the holiday entertainment that is no longer presented, for instance, if you want to stick to one theme) and cause you to rethink where you'll be spending your hard-earned $$$s.
If you just rant and whine about one thing, they're more likely to not take you seriously and to send you a canned response (I am sure they've been working hard on one with Marketing and Press and Publicity as well as Social Media since this exploded).
Showing this the last proverbial straw will be more effective in communicating.
