I would kind of like to read through this thread (200+ replies, wow) but the spoilers are quite rampant here, my bad, I did put a warning in the thread title.
I'll make the point however, that the difference between this and Fallout 3 is that the ending for Fallout wasn't changed due to the entire internet whining, it was changed because Bethesda themselves found the ending to be lacking. If BioWare come out and admit that "yeah we thought that ending sucks, we're sorry, we'll sort something out", then fair do's, like I said, they have the right to change whatever they want, but no-one has to right to pressure them into doing it, and especially not demanding it.
