I for one experienced personally when they invited my friend & I to discuss buying our app. They just wanted our secret sauce & after baiting us with promise of working together they us kicked us out and said the race is on.
Now there was no guarantees we’d be working together but two guys with no connections is tricked by Google and told the race is on? Us vs. Google who later is granted patents for what we met them about.
Now everyone says that’s just how Silicon Valley is...its expected. Hmmm things change!
Ay, there's the rub, innit?
This is the same comcast we're talking about right? The one that's spent millions lobbying for the right to monitor what their customers do online and sell it to advertisers?
Are you sure you are not both? ATT gives you a discount on your monthly fee if you allow them to inject their own ads. It was opt-in, but it would not surprise me if they don't just do it to all users. Plus, if you are using their DNS, I'd assume they are slurping in all of that data.
