To some extent this misses the distinction between style and substance. People who read a lot, and/or who evolved at a time when critical reading was an essential skill, can be relied on to distinguish between conveying an idea versus

I hope the article's authors aren't taking the position that mass surveillance is a bad thing, signifying a breakdown in civilized norms ... after all, they're using the same methods to "track the trackers."

All true, all good points. Some day partitions and their unique UUIDs will be the sole valid identifiers. Then end users will have to be warned not to copy entire partitions including their (no longer unique) UUID. Sounds bizarre but I'
