You're welcome to go back further, but it's mostly commentary on the current state of those companies. Google / FB / others have become significantly less innovative as time has proceeded. They are almost entirely driven by their core product (with little changes, despite comments suggesting incremental innovation - not enough to justify thousands of devs) and acquisitions. Others, like Apple and Microsoft, seem to be more willing to innovate internally.
