That's not accurate. The $50 is for a full year of App.net service. That's all. Where is the binding agreement that that says what you are suggesting?
People like to quip that if you aren't paying for something, you are what's being sold. Frankly, the same is true even if you are paying for something. We should have learned by not that unless it's spelled out, we should be wary. After all, if App.net gets bought out, you've effectively paid to become the product.
So, what rights is App.net giving you for paying $50? What promises have they made that can be enforced?
Take this:
> We will never sell your personal data, content, feed, interests, clicks, or anything else to advertisers. We promise.
Maybe I'm just cynical, but that doesn't mean much. I mean, you don't have to sell the data to sell being able to advertise using that data. It's very easy to get away with saying this and still provide data to 3rd parties or allow for advertising to target users.
My hope is that App.net is sincere. But unless they've hidden it, nothing on their site suggests they are doing what people say they are doing.
