Since I started to work for big tech myself this is what I tell people most of the time: Stop thinking about complaints, start thinking about solutions to problems that everybody has. That is where the power of big tech comes from. I mean, facebook knows all our social contacts because it's the best way to communicate over long distances and having different live situations. Gmail can learn how we write and think because it's the best and most flexible mail client out there. Google and Apple can spy on us via smart phones because these devices have gave us so many opportunities like navigation, translation, communication, photos etc.

Start building a better future and you can be part of defining what it will look like. Doesn't even have to be a competitor. Employees inside the big tech companies also have more push towards their personal goals than people outside.
