The fight for Internet Privacy, it's allies, and Demand Progress are hosting a movie night on Sunday 17th November 2013.
This movie is about how large corporations and the government's are tracking information via technology and the internet.
So, basically, are you really sure about all those terms and conditions you simply clicked 'agree' to?
Twitter. Your images still belong to you as the content poster, however they can re-use them if they wish ("a worldwide, non-exclusive, royalty-free license (with the right to sublicense)").
LinkedIn. Can pretty much do as they wish with your data too. Oh, and your ideas, analyse them, commercialise them ("copy, prepare derivative works of, improve, distribute, publish, remove, retain, add, process, analyse, use and commercialise, in any way now known or in the future discovered..." )
Facebook. Hey this big company can do what they like too with your uploaded content. Don't want that any more? Deleted your profile? Shame all those other people interacted with your content, because Facebook is allowed to keep hold of it till all ties are gone.
Google is limited to operational, service improvements and promotional material. Google+ i'm not too sure on, but be my guest and read the terms then fill me in.
I personally use all of the above, and while the terms may be interesting and sometimes worrying, I already agreed to them, and can't change it now. Future terms are different, you may notice the app permissions on mobile phones the request things that they don't need. For example, why does a product listing site require access to all your contacts, phone calls, call history and SMS? I don't know why, and for that reason, I don't install them.
