Recent revealing of US and UK efforts in deliberate weakening of civil cryptographic systems just confirms the well known fact: no one can trust proprietary or "closed"-source software in aspect of privacy and security. Though use of Open Source software and open systems could be a solution of this problem. Bruce Schneier give some useful tips. But it seems to be a bit difficult to maintain private communication, due to the fact you cannot force other people to use same secure tools. Even it is illegal to use cryptography without "backdoors" in some countries like Russia.

By the way, most of people do not care on personal privacy. Obviously, if you store your files and mail in "cloud" service provided by Google, Microsoft or other company, with slight encryption or without any - you should understand that this information could potentially become public. But seems, there is no problem of this for the mayor part of Internet users.
