You use a profit making entity (hopefully) without paying for it. They have a RESPONSIBILITY to their shareholders to maximize the profit. It MUST come #1 in priorities, that is why people gave them money.
You accepted you have NO rights in the use of it, it is there, you use it, and you HOPE it does what you intended. No matter what the docs say at the moment. They reserve the right to change them, you agreed to it. If you think otherwise, then you will be sad.
You have not provided anything of measurable individual value to use as any type of negotiating leverage. You are not a stakeholder. You are a sheeple. You are not the customer, you are the product.
Any "agreement" is nothing more than a bullet list whipped off someone's PC, posted for your entertainment. It is meaningless.
and yes, the same rules apply to G+.
