Terms and conditions are NOT copyright law. They are a separate agreement that is the companies "wishlist" of things they want the consumer to agree too. It's common for them to spell out terms in direct conflict with copyright law.
The reason that an iTunes video purchase is encrypted is because it is illegal to break the encryption in order to make a copy (DMCA). However capturing the playback and transforming it to another medium is for personal use is fair-use.
There is also no time limit to how long a person can save the copy for. As long as they had legal access to the content at the time of making the copy. For example say I recorded a football game from a streaming service. I can save that copy for personal use for the rest of my life even though I purchased a one time only streaming.
My personal theory:
First off, raw milk does taste noticably different than pasteurized and homogenized milk you find at the store.
Pasteurization: heating the milk triggers the unfolding of proteins (Denaturation). This is what kills the bacteria but can also change the flavor of the milk.
Homogenization. This process breaks up the fat into smaller segments so they stay in solution in the milk. The result is a less creamy flavor.
People instinctually associate flavor with nutritional value. They think that better flavored food = better for you. This sort-of works in tomatoes and a few other fruit/vegetables. However taste perception is a complex blend of genetics, environmental conditions, and psychology. So the results are inherently unpredictable and completely unreliable.
The unpasteurized crowd all fall for the 'it tastes better so it must be better". They then make all sorts of excuses to justify their instinct. " Big corporate milk is evil!!" Blah blah blah.
