Fingerprinting? This is just clickbait. Identifying that the murder weapon was a knife isn't remotely the same as getting the fingerprint of the killer.
Context matters. In this case "fingerprinting" refers to fingerprinting of the protocol by a DPI system, and the problem the author is concerned with is the ability to use a VPN at all.
It really is fingerprinting. It’s just showing the fingerprint of the service and not the user. This is a very normal usage of the word for people interested in identifying specific types of traffic. Lots of things different things have detectable fingerprints that are useful within certain contexts.
Fingerprinting doesnt mean "uniquely identified an individual", it just means "uniquely identifies some aspect of the target". You could fingerprint 'firefox' amongst all browsers, or in this case they are fingerprinting OpenVPN amongst all traffic.
it is. what if we know that only one person had said knife and then this "fingerprint" would be 100% empirical support. So yes sometimes just noting a VPN was used with said foreknowledge is enough to correlate and prove something.
