"You are out of you mind if you honestly think that I am going to trust my entire desktop and all my data to someone else's computer, to be accessed under someone else's whim."
People have nothing to fear from a connected society where communications and data can be accessed by government or big business.
Apart from political & social activists, business people, people working for those groups, the friends and family of them and the wider populace who benefit from the rights and safeties that were fought for, won and maintained.
But unless you're one of them, nothing to fear.
