They haven't crippled a damn thing. Typical over exaggeration much? Of course some people will "be mad", because some people seem to get tomato face angry over a few FPS here and there.
iOS 10 beta runs just as good on my 6 (which is almost a two year old model now) as iOS 8 that shipped on it when new.
iOS 10 has a huge advantage than no iOS has had since before iOS 8. And that is the kernel is no longer encrypted. Which translates to being able to optimize the OS better (a statement Apple even made)
A prettysignificant portion of this guy's post history follows this pattern. He even claimed to have his phone bend in his pocket on the first day of bendgate. He's one of money of Apple's abuse victims.
Anyway, this beta is by far the clunkiest first release since 7.0. Which is a great thing and it actually runs pretty well when you factor out some of the stuttering associated with development apps running the background. It means the devs have a lot on their plates. I do find it strange when some people complain about their phones getting slower as updates roll out, as if there's some sort of denial that every single product with a progressive operating system will face the same consequences.
Maybe as a compromise, we can let this guy keep his iPhone 3GS on iOS 5.3 and just disable the app store. And Messages. And Safari. And any other app that, if compromised, could then start sending out malicious code to more up to date devices it interacts with. They can call it...The pHone.
