It is important to discuss because its the INTENT behind what is being done, not so much HOW they are doing it technically - we 'technologists' love to know the how, but everyone needs to know the 'WHY' -- especially non-technical users.
Just because most people are non-technical does not make them stupid... and it doesnt remove their humanity, which, as unpopular as it may seem, throughout human's entire history there was more privacy than there has been in the last 75 years.
So, as we have evolved with actual privacy (due to lack of adequate/developed survellance technologies), and its idiotic to say that humans should have no expectation of privacy.
Then why are you wearing clothes? is the intimate nature of your body not referred to as "private parts" -- so there are "private thoughts" and "private personal details" that shouldnt just be available because "government" says so...
