Because what you see that we call mold is the fruit of a vast root system. In hard cheese if you can cut an inch or two in every direction from the mold you likely will get the root system with it. With a soft cheese (or bread) that root system is likely spread through the food pretty thoroughly.
I love Star Trek Lower Decks but it’s really clear lately that the assholes at the top (of all profit oriented entertainment megacorps) don’t give a shit what the users want. Only a new user is important as that increases cash flow, the idiots who are already paying are at their whims.
