I'm a veggie, but I don't have a problem with "protective atmospheres" in food packets. It keeps things fresh because it keeps bacteria down - all to the good!
And while we might find that part-baked bread, deep frozen for months, is a bit distasteful as an idea, it's really no worse than a can of beans with a shelf life measured in years, is it?
(That said, there's nothing quite as good as home-made bread!)
