If FT's claims are based on the interview material they show in the posted video, they're making a very liberal interpretation. As far as I can see, Gates only made a few specific points:
Overall, he seemed to take a lot of care to avoid taking a clear stance with Apple or with the FBI and framed the whole situation as though it was an important legal question that should be settled by due process. The claim that he said "technology companies should be forced to co-operate with law enforcement" is misleading.
Computer programs expand so as to fill the core available.
