The headline seems pretty misleading. Here’s what seems to actually be going on:

> Every time you open LinkedIn in a Chrome-based browser, LinkedIn’s JavaScript executes a silent scan of your installed browser extensions. The scan probes for thousands of specific extensions by ID, collects the results, encrypts them, and transmits them to LinkedIn’s servers.

This does seem invasive. It also seems like what I’d expect to find in modern browser fingerprinting code. I’m not deeply familiar with what APIs are available for detecting extensions, but the fact that it scans for specific extensions sounds more like a product of an API limitation (i.e. no available getAllExtensions() or somesuch) vs. something inherently sinister (e.g. “they’re checking to see if you’re a Muslim”).

I’m certainly not endorsing it, do think it’s pretty problematic, and I’m glad it’s getting some visibility. But I do take some issue with the alarmist framing of what’s going on.

I’ve come to mostly expect this behavior from most websites that run advertising code and this is why I run ad blockers.

Expecting and accepting this kind of thing is why everyone feels the need to run an ad-blocker.

An ad-blocker also isn’t full protection. It’s a cat and mouse game. Novel ideas on how to extract information about you, and influence behavior, will never be handled by ad-blockers until it becomes known. And even then, it’s a question of if it’s worth the dev time for the maker of the ad-blocker you happen to be using and if that filter list gets enabled… and how much of the web enabling it breaks.
