Is all business exploitation? And capitalism is the problem? Businesses have to have customers and users to survive, even tobacco companies provide value to users even if their product kills them. If Facebook provides 0 value, stop using them and all the other rational people will too. If they provide a modicum of value, then people will use them if the value delivered is below the cost (cost includes privacy violation and bad trust).
