It's not that the cellulose is harmful, but that it might be used as filler in quantities far in excess of what is necessary for preventing caking. Calling it "wood pulp" is pointless scaremongering, I agree. Cellulose on pregrated cheese is also supposed to impair melting, but I've always questioned how strong this effect might be. I've used grated cheese that melts wonderfully and grated cheese that might as well be plastic, and that's generally been correlated with the price of the cheese. Maybe cheaper cheese has more cellulose, but in my experience it's also drier and more rubbery, and melting is influenced by moisture content.
