WTF! Facebook and Google +?

[Mike]

So past week on Facebook and google plus Ive noticed 2 things

First on Facebook every day my computer tries to download files when Im on it, they range from few KB's to 2GB's. The 2GB file was being downloaded without me being informed but the smaller files would show up in my downloads.

As for google plus I couldnt sleep and read the terms and conditions and its saying by agreeing to the t&c's Im letting them know my location, contacts details (so like my grandmothers details on my phone are being given in even though she has never even used a computer) allowing them to use my camera and mic and lot more weird stuff.

Am I the only one who thinks these major social networks are pushing stuff to far ? Like why does google need to use/know any of that ? and whats the 2GB file Facebook was giving me ?

So give me your opinions and ideas and Im gonna go delete and google +
