Actually, it's less
complicated than that...
And remember who Singer consulted with about his time travel ideas?
Seriously, the idea that something else has tampered with time leading to a Sentinel DOFP future is simpler
than trying to explain how these rather conspicuous big ass robots have been running around throughout the original trilogy 'protecting humanity', and yet somehow never made a noteworthy appearance or mention of any sort in any of the mutant shenanigans.
