Apologies mean nothing without a believable promise to not behave similarly in the future. Furthermore, "sorry" doesn't excuse all behaviors. Doing something shitty like closing someone's account without warning and without an appeal process is inexcusable.

I think also apologies require explaining what changes they made and why they decided to do it that way. A look behind the curtain on why they chose way A when they could have chosen way B is illustrative to users.
