With reference to the way hops are repackaged, varieties like Galaxy and Amarillo are brand names and trademarks. Breaking up bales of these hops and re packaging is in my eyes the same as the yeast, where there are no assurances on the QC of the product. Re packaged hops have also been exposed to the atmosphere and have undergone some level of oxidation in the packaging process (not that I care). Additionally who is to say that some unscrupulous operators aren't 'cutting' their high demand varieties with something else, potentially damaging the good name of a particular trademark?
Just saying, not implying that this actually occurs.
