AudioContext latency information can be retrieved without the user's consent or knowledge on websites that never ever use audio. It's a security disaster. I know for a fact that AudioContext is routinely abused on ad networks and by anti-fraud solution providers. Given its widespread use for purposes it wasn't designed for (in fact, this information is used primarily for tracking and spying), it's safe to say it's a tracking scheme.

The fact Google directly and knowingly benefits financially is a smoking gun. They don't give a damn it's not a secure -- in fact they profit on the fact it's a leaky sieve.

You said AudioContext is sometimes used for purposes which benefit the user. Well isn't that swell, the user is maliciously tracked by this security exploit 99% of the time and gets to reap the "benefits" 1% of the time.
