I think the general criticism that new models fail to break ground like they used to, but have barely slowed down their release schedule or extended their support, is also a valid one.
But the author barely touches on that before getting distracted by “phones are too big,” which they then come back to a further three times in unrelated paragraphs.
That’s fair, although I don’t feel it’s changed much for iPhone, past the first few models where the hardware improvements were most dramatic. 2011’s iPhone 4S had five years of major updates supported. The 5S (2013) had six. The iPhone X (2017) is probably on its last major version at seven years. That’s a slow improvement, which still deserves recognition I suppose.
