Obviously they went back on that, but they never said theyd port the system 1:1

Actually, that it not the case. There was an interview, and as an example of adapting the rules for a computer game, it was mentioned that with bad luck, at low levels you could miss a lot, and that was not fun alone on a computer, compared to the table top environment where you are at least interacting with your friends.
Many people just interpreted doing something about possibly missing a lot at low levels to mean that there could never be anything that misses, for any reason. I suspect there could be some overlap with the people now saying BG3 looks exactly like D:OS 2.
