Reasons not to use Facebook

• Facebook is not your friend. Its "real name" policy is enough reason to refuse to use it, but there is so much more nastiness in Facebook.
   
• If Facebook achieves its goal of becoming the main publication site for journalism, it will be a new chokepoint for censorship.

Reasons not to use Facebook

• When useds log in to a site through Facebook, Facebook gives the site access to lots of information about the user.
   
• Predicts who new useds know, based on their phone lists and email address lists. Along with the phone and email lists of all the other useds.
   
• The NSA tracks Americans' social networks, and Facebook is just one of its sources.

Reasons not to use Skype

• 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.
• A nonfree program denies users freedom, which is unjust in itself. Making the ethical issue sharper, for you to use Skype is to encourage someone else to use Skype, which means you're pressuring someone else to surrender freedom as well. This is plenty of reason to refuse to use Skype, but there are more reasons.

Reasons not to use 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.

Reasons not to use Skype

• Microsoft has changed Skype to make it easier for states to snoop on users.
   
• Skype messages are not encrypted for the whole trip: Microsoft can read them. And Microsoft does read them.

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.

The Danger of Ebooks 

The Danger of Ebooks 

• You can buy one with cash, anonymously.
• Then you own it.
• They don't know what do you read.
• You are not required to sign a license that restricts your use of it.
• The format is known, and no proprietary technology is needed to read the book.
• You can give, lend or sell the book to another.
• You can, physically, scan and copy the book, and it's sometimes lawful under copyright.
