The whole article is exceedingly disingenuous though. Which makes me not really believe their objections.
For example, calling it a "creating a whole new OS" is basically a lie. Saying it would weaken all devices is basically a lie. Unless what they mean to say is they cannot fathom a way to make a firmware that only works on one specific phone. But if that's the case they should have said that.
There's an entire section in TFA where they specifically say that it is not technically infeasible.
