Heck, I can't keep up. Did you say or never say there was no market?
Yes, I'm saying exactly that, but neither you, I, nor anyone at Apple knows for sure, because it's impossible to know for sure. Apple isn't omniscient, Apple isn't perfect, Apple isn't immune from making mistakes or misjudging customer preferences, and they aren't above placing short term profits over long term customer satisfaction (at least that last point you tacitly acknowledge).
No matter how well Apple is doing, they can always do better. If any of Steve Jobs' spirit lives on in "Apple's DNA", as Tim Cook claims, he'd admit that as well. Hopefully, it's only on MacOS Rumors forums that you'll find people who insist Apple can do no wrong, that they have perfect market insight, and that whatever they are offering is exactly what people want. Because if that kind of hubris is within Apple, five, ten, twenty years from now, they could be looking back, wondering where all their customers went.
History is full of companies who thought for sure their marketshare was impenetrable and that they had a unique understanding of customer's needs. IBM, Nokia, and Microsoft are recent examples.
Do I know for sure that there's a market for a modern iPhone SE? No, though I think there is. That's the key point: Where you assert that you, or Apple, knows for certain that there is no market, I've got the humility and honesty to say that knowing this for certain is impossible. If knowing exactly what customers want and are willing to pay for were possible, no business would fail. Heck, customers don't always know what they want themselves. Jobs famously knew this.
Apple's free to ignore the potential SE market. Maybe that's the right business decision, at least in the intermediate term. But for one last time, just because they've chosen to ignore the market, prudently or not, is not evidence that the market doesn't exist. And yes, you've stated exactly that.
