You stated that Apple used to introduce ports in a gradual fashion in 2000-2016. I presented a few counterexamples (most of them in the 2000-2016 range). I wasn't reframing your statement. But don't worry, I don't get angry over internet discussions
That's cherry-picking.
That's... a whole different media, for a totally different use case.
There were 4 iPhone models that had both lightning and a headphone jack. 30-pin was substituted by Lightning/USB-C, not the headphone jack. The headphone jack was simply removed. The 30-pin connector already had audio capabilities, even.
My point, exactly, against the inclusion of Thunderbolt 2 after Thunderbolt 3 had been released.
Why? Thunderbolt 2 didn't sit side by side with Thunderbolt 3.
You can keep repeating that if you want, but it's not going to become true. Apple has been adamant to remove I/O standards as soon as they believed they were becoming outdated long before 2016.
