Aggiornamento 28 aprile 2016: nell'articolo sotto riportato, Richard Stallman indica alcuni buoni motivi per non usare Skype. Per le videochiamate, consiglio ai miei lettori di avvalersi dei servizi web basati sullo standard aperto WebRTC (voluto dal World Wide Web Consortium), che è uno dei più sicuri per le comunicazioni VoIP, come descritto in questo report molto preciso: http://webrtc-security.github.io/
Servizi di questo genere sono ad esempio Firefox Hello, oppure https://appear.in/
Ho tratto l'articolo che segue il 21 luglio 2014 da: Richard Stallman's personal site - https://stallman.org
Skype requires the use of a client program that is not free software; in other words, the users don't control it — it controls them.
You should never run a nonfree program, so this is enough reason to refuse to use Skype. But there are other bad things about Skype.
- Skype refuses to say whether it can eavesdrop on calls. That almost certainly means it can do so.
- Skype gave personal data about a Wikileaks supporter to another company without any legal obligation to do so.
- Skype churns the meaning of preference settings, and gives its users a run-around when someone cheats them.
- Microsoft has changed Skype to make it easier for states to snoop on users.
- Skype messages are not encrypted: Microsoft can read them. And Microsoft does read them.
The author of the first article ended by bending over backwards to legitimize everything else that is wrong with Skype, such as the use of a nonfree client program, but you don't have to follow him in that.
What to use instead? The most obvious alternative is a long-distance phone card. They are quite cheap nowadays, and they work with any phone. There are also free programs you can use, such as Ekiga, Mumble, Jitsi and more.
