I'd think facebook is scsry for me because i myself am a heavy user of it and almost all my apps are synced up to it so I don't need to enter my passwords all the time. That being said, there is alot of pertinent dta there about me. Although this data in itself is not important, but combined with others, it's dangerous.
Amazon is the most scary company in the whole world. You can talk about oil companies and finance companies all you want but regulations are getting tighter and tighter for them, the more mistakes they do the more punishments and taxes they are getting and after 2008 the finance world has been getting much more careful and conservative whereas after BP oil breach on ocean the oil companies are much more careful as well.
Yet here is amazon, whose workers DIED on company work, whose workers pee on cups so they don't have to go to toilet, whose workers have feet problems from walking 12km A DAY EVERYDAY. I mean amazon is as horrible as it gets, there are many other stuff that casts a bad shadow on them as well.
