As you already know there are always alternatives[B]!![/B] like Google and other ways to make calls, chat and send files over the Internet, however in this day and age of digital information there is little chance of finding real privacy.
There was an article a few years back about Skype monitoring calls (chat or video) and even recording some of them, and with the controversial business practices surrounding Google when it comes to privacy so there can be a trust concern there too.
Law enforcement and other such special agencies connected to governments have been given a much broader range when it comes to the surveillance of on-line and even offline data, this is mainly due to hackers and security breaches in companies, state and government agencies.
Course most people don’t have anything to worry about though because if there is any surveillance being done and you are not braking the laws any monitoring that may or not be in place will be short.
Tis just my .02Â¢
