I know some people think that using hyperbole for effect is a thing. They tend to be very young, smart people who are starting to realize what they're capable of but are still trapped on the wrong side of the Dunning-Kruger curve. The most common defense people give is that they assume the reader or listener knows that the hyperbole shouldn't be taken literally, and that they're really trying to convey how strongly they feel about their much more reasonable actual opinion on the matter.
However, to me (and, I would hope, to most people), hyperbole in technical discussions means that the person is either immature in a way that makes them less credible, or that they are lying to me and assume I'm dumb enough to believe them. Or it's clickbait, or all of the above.
I don't think the author(s) of this site are any of those things, but I also know that Yosemite as a whole is not designed to take away 100% of your privacy, which is what the title implies. This is also what turns me off about a lot of FSF propaganda, and most politicians regardless of their beliefs.
