This Antifeature is applied to apps that promote or depend entirely on a non-Free network service.
While this is a rather vague definition, the following might give some sort of guidance:
The term is not clearly defined. I think we most of the time were actually talking about the code aspect of it: Does an app rely on a networking service that is not (by our knowledge) run or easy to reproduce with free software. Sigh.. don't think that makes it any better. Maybe some examples help: Telegram requires interacting with a server which source code has not been released, so its NonFreeNet. On the other hand, serving html files from an MS IIS http server is not affected, because you can easily replace it with your favored one. -- Krt (talk) 08:56, 24 November 2016 (UTC)
