1. They never promised they will try to replicate 5e as closely as they can, not even in the slightest. If you actually look at the interviews, when asked about the level of faithfulness they always said that they are using the 5e ruleset as the basis but changing it to fit the new medium better (this doesn't mean only changing stuff that can't be done on a computer, but also to make it more mechanically engaging since you aren't just describing what you are doing)
They must not (yes, MUST not) call it DnD then.
2. It's your fault if you bought an early access game and are disappointed. They were very clear that the purpose of the early access is for us to playtest the game, and it's not even close to fully realized.
True, but agin it's totally their fault if they lured people into buying the EA game by using links to DnD. Was it just BGIII it would be fine, but when you await to feel some underbaked due to EA NWN and get a poorly camouflaged DOS instead it's extremely disappointing.
The changes they've made to the mechanics of 5e are, going by basketball as the example, more in the line of playing with a basket the size of a hula hoop, and the rule that whenever you hold the ball you're not just allowed to take more steps but nobody on the opposing team is allowed to move at all.
Nobody cares about whether or not they follow 5e to the minutia or not. People care about the changes they've made from 5e because they're making the game worse and less fun.
So true.
