I personally think its misleading and even when you start reading the page it links to is even more misleading in my opinion.
>Every time any of LinkedIn’s one billion users visits linkedin.com, hidden code searches their computer for installed software, collects the results, and transmits them to LinkedIn’s servers and to third-party companies including an American-Israeli cybersecurity firm.
When I read that, I think they have escaped the browser and checking which applications I have installed on my computer. Not which plugins the browser has in it. Just my 2cents.
