What Larian rolled out is effectively a demo that is updated every so often. It was never advertised as a "live" EA title that is constantly updated and kept boiling so that the studio behind it can keep its head above the water, or as an indie team's first project that they hope to fund this way.
While I agree that the feedback could be more two-directional, given how many things that even people who like how the game is shaping up still want changed, this isn't a "we release the game in chunks as we complete them" approach. We'd probably have Act 2 by now if it were. And it was more or less the same with D:OS2, as well.
