Why you shouldn't use Skype
Skype client program is nonfree software: it gives its owner power over its users.
Skype have absolute control over all communications going through their network.
- Skype is abusing this power with attacks on privacy, data retention, censorship, and eavesdropping.
- Skype refuses to say whether it can eavesdrop on calls. That almost certainly means it can do so.
- Microsoft has changed Skype to make it easier for states to snoop on users.
- The Chinese government, was found to have been spying on Skype conversations. And they are probably not the only ones.
- Skype gave personal data about a Wikileaks supporter to another company without any legal obligation to do so.
- Skype messages are not encrypted: Microsoft can read them. And Microsoft does read them.
- Skype churns the meaning of preference settings, and gives its users a run-around when someone cheats them.
- Skype workings are kept secret and substantial efforts are made to prevent reverse engineering.
- Skype uses closed, secured-through-obscurity network protocol that takes freedom away from users. Skype's technology forces people to join the walled garden in order to keep communicating with others, and locks them in (ouch!).
- Skype's 2005 independent security review admits a caveat to this protection: "defeat of the security mechanisms at the Skype Central Server" could facilitate a "man-in-the-middle attack" (see section 3.4.1). (from article: EFF: Why Doesn't Skype Include Stronger Protections Against Eavesdropping?)

- For instant messaging, calls, video calls, file transfer use TOX!
- For instant messaging, group chats use XMPP (Jabber)! Good clients are Ekiga and Pidgin.
- For text and file transfer use OpenPGP encrypted emails (Enigmail plug-in for Thunderbird)!
- Still is to be proven good: for calls and video calls use web-based WebRTC clients. Please let me know if you find a good one.
