While I doubt the hand sanitizer, plexiglass, and other measures were particularly useful in themselves, I also suspect that the constant reminders of the pandemic and the fact that it was present even within the magical berm caused an increase in caution among guests which did have an effect, if only minimal. I also believe the measures reducing indoor capacity did make a difference. But at this point we’ve all just given up, so all we can do is blame WDW for following the general trend. I’m resigned to being the one weirdo in a mask when indoors at the park.I think it's more that Disney has recognized that scientifically speaking, this wasn't really accomplishing anything in terms of preventing Covid transmission. I think it was more a ploy to attract guests with the veneer of safety than anything else, and since that no longer seems to be a concern (i.e. guests are showing up in droves), they're giving up on it.
