To an extent.
The thing I kept hearing about DME is that it was operated by Mears and the contract's renewal time was coming up. With the train-shuttle-thing coming there's just an unfortunate overlap where a new contract (likely) would have been ongoing during the time the truttle was available. I agree that it's not a good idea to just get rid of the service altogether, and I was only going to the parks when it was offered so it will be weird to adjust without it, but I'd like to hear more specifics about why exactly it was gotten rid of. Anyway, I think it would have happened despite the pandemic.
The Fastpass thing wouldn't make much sense to me...I'm surprised they aren't actually using it more often since it acts as a sort of virtual queue and would keep people separated a bit more/allows for trickle-in. Maybe there's some weirdness with the current park pass system and fast pass stuff, but I remember only getting to pick one park beforehand...I don't know.
I wish that they had used to lower crowds to make some more positive changes. Which they are, to a point, even though the Epcot stuff was happening beforehand. I certainly don't envy Chapek and D'Amaro.
