There are news all over Internet about Microsoft spying on its Skype users. You can read a lot like this http://www.zdnet.com/is-microsoft-reading-your-skype-instant-messages-7000015388/ Whether the news is true or false, people use skype, because they do not find a perfect alternative for it. We have Ekiga, When I tried last time, it does not even established connection properly. Now I recently came through Jitsi - A Free software under GPL which looks promising and available cross-platform. If this functions well, it has the potential to replace Skype, and I have just installed it and will try and post my review on it sooner or later. If this is worth, then we have to promote this tool as a community behind Free Software and Open Source.
