These all seem like drawbacks to me. So I suppose the question is, which of these drawbacks are real? For instance, if I say a drawback of eating potato chips is that they can break into sharp edges and cut your mouth like glass or a paper cut, then obviously although this is a drawback, it's fake because this is totally not true.

So can you eliminate any of these as being false?
