You're arguing out of both sides of your mouth and contradicting your previous comments.

I'm not, and I explained exactly how I'm not in the section you quoted.

stated that manufacturers put things like a headphone jack into a phone that seems like it was built by Fisher Price and then point to it's lack of sales and claim "people don't want headphone jacks"

What does any of that have to do with small phones, though? You seem to be implying OEMs have a some sort of agenda against small phones. But why?

I'm saying that consumers don't always act rationally

Why does that matter? OEMs are not going to continue manufacturing phones that consumers aren't buying because they're irrational. That would, in itself, be irrational.
