I listened to the entire interview the Luke Smith excerpt was taken from and had the exact opposite reaction as the OP. It was a remarkably refreshing, candid interview that was decidedly free of BS. Admitting the state of the lore in Destiny - which was apparent for all to see - and laying out the plan to re-establish it and build toward a conclusion is exactly what I want this series to do. So I was really happy to hear that.
Really, if Bungie being candid about their failings in D1 and their plans for D2 is what constitutes "upsetting the fan base" then we're either deep into hyperbole territory, or dealing with people with no perspective. Or both.
The rest of the list are a mix of intentional design decisions that come with sequels and statements that certain things will not be there at launch - implying they'll come later. A huge swath of Destiny's features came after ship, and it's not really reasonable to expect feature parity at launch for Destiny 2. Partly because it's a different game, and partly because they gotta ship the thing. Adding private matches after release is not a biggie.
D2 is in this space where when Bungie makes changes they get people upset, but it's simultaneously not different enough to be a full sequel, for some. Just imagine if they upended the core gameplay.
The only change I'm actually upset about so far is limiting PvP to 4v4 modes. I played almost entirely BTB in Halo, and 6v6 modes in Destiny, so it's a major turn-off for me. But then I play relatively little Crucible and also understand why (design focus). Meanwhile the suite of new activities in the open spaces sounds freaking great, so I'll take the trade off.
