Are you defending LinkedIn’s behavior right now or are you just happy to be more technically correct (the best kind of correct!) than those around you? Trying to understand the angle

Something may be bad, but accurately describing why it is bad significantly elevates the discourse.

Eg, someone could use the phrase "Won't someone think of the children?" to describe a legitimately bad thing like bank fraud, but the solutions that flow from the problem that "children are in danger" are significantly different from the solutions that flow from "phishing attacks are rampant".

The two issues in this case aren't quite as different as child-endangerment and bank fraud. But if the problem was as the original title describes, the solution is quite different (better sandboxing) than what the actual solution is. Which I don't know, but better sandboxing ain't it.

The browser fingerprinting described is ubiquitous on the internet, used by players large and small. There are even libraries to do this.

Like OP, I don't consider behavior confined to the browser to be my computer. "Scans your browser" is both technically correct and less misleading. "Scans your computer" was chosen instead, to get more clicks.
