Whether you liked it or not it was held back from the iPhone 4, rendering your assertion that you get two years with full iOS updates moot. By the way, I did not and do not find Siri useless. Granted I think Google Now is a bit better but that is besides the point.
It's also a fact that it happened a year after the 3GS was released when iOS 4 came out too: no multitasking support, no task switcher, no orientation lock, no lock-screen wallpaper, and no bluetooth keyboard support.

Even back the the sympathisers justified it and we're proven inherently wrong by the jailbreak community. Not much has changed since then sadly.
