At this point it's being angry for the sake of it.
A few years ago I bought a Nokia N900 which was at the time a 10 year old phone. I did this to use it as a daily driver.
Without community support the phone would have been useless. But, more importantly, if the phone required an internet connection to some server in order to let you replace the stock OS then it would have been a brick because Nokia's servers were long gone by then.
That being said, all things considered, the most important argument here is not of the practicality but the principle.
You handed over money for a piece of hardware but you can't make full use of the hardware until you let the phone talk to the manufacturer once. Thats completely insane irrespective of how small of a perceived issue you think it is.
