Two problems with that.
First, the choices in The Witcher 2 are the same as BioWare's because it doesn't really change the plot per-se, it changes the narrative around it. The plot is ultimately always the same in the end.
But it did change the plot. You can go to one of two places and get a different set of quests in each area. Sure, the game ends the same, but the important thing (the thing that people notice) is that there are two substantial and mutually exclusive paths.
You are right about the Ogre Battle games, but those were self-contained Which leads me to point two, Andromeda is not going to be self-contained in any form, and we kind of know that going in.
Perhaps the problem with that disconnect is that people expect too much from choices and consequences? Should every single thing you do have a massive impact? Realistically, no, so cosmetic changes are fine in the end, that's part of roleplaying. Hell, a good GM would be able to take the actions and choices and modify what is going on in their own stories to continue the plot; the only change is the narrative around it.
It's basically BioWare telling their players what they have been saying all along; here is the plot, you have some freedom with it but we control that part in the end. If people don't like that or expect every single choice they make to be a defining moment in history of some kind...I can see why they would be upset, but thats the way it always really was...
Many players aren't that rational, though. Nor are they well informed enough about game development. They can look at Witcher 2 and say "that's the new standard!" without really realizing the cost of making that 2nd act happen.
I was never very salty about ME3's ending ignoring our decisions because I knew that tons of different end states is a difficult task (and I thought there were more pressing issues with it, of course), but that's probably not what you're going to hear from most detractors. Tell people their choices matter (and throw the word "reactive" around enough) and a good portion of them will probably expect more than cosmetic consequences.
