Ah, yes, "choices matter". I thought we have dismissed that claim.
Telltale/BioWare(EA)/some other studios love to use this "your choices matter" as a sell point, since people just love the illusion of choice (insert Architect's speech from Matrix here). Yet it is a highly debatable point, and it all comes down to how you define what counts as "choice matter"
1. In a way, previous choices "matter" because it does alter your game experience a little, but it is simply cosmetic. Sure, there are codex changes here and there, you can see different combos between hawkes and warden allies, and some cute cameos or references to pander to the fans, etc. But does it really impact the narrative in a meaningful way? Not really.
2. I, along with some others, don't think previous choices matter because everything you did essentially does not impact anything substantially. Alistair/Loghain/Stroud serve the same funtion, King/Queen of Ferelden always have mages in Redcliffe, whatever happened in Redcliffe does not affect the current situation at all...this list can continue, but the point is simple.
Am I suprised/angry? Not at all. Even if the devs/writers have amazing ideas of having dramatically diversed narratives depending on previous choices, it is possible but extremely unlikely for the higher-ups to approve considering the associated cost and benefit.
