I don't agree there are "no shows." We saw quite a few shows in August. The circlevision shows in Epcot, Muppets and Lightning McQueen in HS, Tiki Room and Country Bears and Carousel of Progress in MK, and sitting watching distanced character appearances in every park. They are bringing the Frozen show back to HS too.
I also considered the resorts to be a major source of entertainment. We spent much more time at our resort--swimming in the pool, than we normally do on a Disney trip and it made me realize how much we were missing out just rope-dropping to close at the parks in past trips..
Two differences:
(1) Go to main street/the hub Magic Kingdom. Count how many people at a given time are standing in the middle of a busy walkway taking pictures. A lot. Now count how many people are sitting down in the middle of main street eating. That's the difference. People don't just want to take pictures of them sitting on a bench somewhere away from other people, they all want a picture of the same things right in the middle of the action where everyone else it trying to walk by and can't distance, i.e., front of cinderella's castle, or the Epcot golf ball, or the tree of life. Easier to have a rule that says "you have to go off and sit somewhere away by yourself from other people if you want to take your mask off to eat" than to have a rule that says "you have to go off and sit somewhere away by yourself from other people if you want to take your mask off to take a photo"--because for photos it kind of defeats the point.
(3) Bad publicity. Someone takes a photo of them eating a mickey bar and posts it to social media, people get it--the person is eating and that's why their mask is down. People take a selfie in the hub without a mask and with dozens of other people doing the same thing nearby, and it becomes a scandal.
I agree that expecting six feet distance while moving around is not realistic, nor is it a violation of social distancing. You have to be standing close to someone outdoors for much longer than the couple seconds it takes to walk past to sometime to be worried about Covid transmission. Social distancing rules are in place for when people are near one another for prolonged periods, or when indoors where the air is not always refreshing. But I will say I don't agree there is nothing concerning about that photo. What concerns me about the photo is that when you put it together to wait times, it really does appear Disney is increasing capacity too much, too fast, with too high a U.S. infection rate. The more people you add to the parks, to more people with Covid will be there, and the more likely you are to encounter one on your trip. Plus, more people makes it harder for the same number of CMs to enforce rules.
I also do agree with the poster of the photo that there were far more people with masks off or worn under noses/chins on our trip--and not just inadvertent, people who were defiant and refused to correct the behavior when asked--than I was led to believe by the posts here. We had many many moments when we were stuck in an indoor line queue with non-compliant people who had to be reminded EVERY marker to go back to their line and put on their mask.
