I wouldn't be surprised if LinkedIn sent this data back, but browser plugin detection sounds like a common ingredient in browser fingerprinting, which can be pretty useful for things like A/B testing signed-out users or detecting ad fraud. I don't place LinkedIn in very high regards, and I'd be surprised if they ever asked a user if they could fingerprint their browser in an unambiguous way, but I don't know if I find this particular thing to be exceptionally evil.
