Large tech firms absolutely have access to unqiue image, text and game(play) data. I'm surprised you think they don't. How many tech startups do you suppose have access to every single multiplayer game of Destiny (Microsoft), every user's profile photo and interest metadata (Facebook), or every user's search history and email (Google)? But wait, there's more! How many startups have ready access to usage statistics for every mobile app (Google, Apple)? How many startups have virtually the entire corpus of available ebooks on hand for mining (Google, Amazon)? What about traffic patterns (Google), or virtual reality game(play) data (Facebook)? Telemetry data from the most widely used operating systems and web browsers (Google, Apple, Microsoft)? Video content with official subtitles (Netflix, Amazon, Google, Apple, ...). And don't forget login and activity data through social login (Facebook, Google) and image training via reCAPTCHA (Google). I can go on and on here. You should reconsider how large the set of training material is that be acquired by mining massive amounts of "personal" data. Of course, this is completely orthogonal to the other major advantage large companies have; namely, they have vast sums of money to throw at compute and storage resources.
