I am not sure what the issue is here? If it feels wrong to play a character a certain way, then simply don't do it. If it bothers someone that others might play a character contrary to how they think they should be played, then maybe don't watch play videos or play the multiplayer with people that don't think the same way. I think this would probably be the safest way to not be bothered by how other people play their game. Most likely companions will have different dialogues for situations that will be based on how they are "supposed" to be, but all the options will still be there to take the different paths and for corruption/redemption stuff.
I think the Origin system is not going anywhere, they have spent too much time on it already and while I may not play as one myself, I am glad it exists. Many people seem to have trouble in coming up with backstories and feel "lesser" than the companions, and some people don't care about creating a character at all and just want to play the game. Origins make it easier for these people.
First I'll just say this argument is completely academic since I agree, the origin system doesn't go anywhere.
But on topic, the reason people are so angry is because there are a lot of resources that go into implementing this system, resources that could have been spent on other revenues. So those who are for the system will say it is a good usage of resources and those who are against it will say it isn't.
Personally I think that not only is it a waste of resources, it also creates unnecessary difficulties on the writing and simply isn't worth it.
But than again, I think this one is a done deal so we should just grit our teeth and move on
