in short the reason not so many ppl are, "up in arms" as you put it. is because as new content is released, it is released with new and better gear, new content bring better gear that makes old gear obsolete, there is no reason to believe what is to come in the future won't be better than materia. materia came after the dungeons that are out so it is better. but 1.21 will have newer stuff that will be better again. if not then complain
