It doesn't 'has to be' that.
The exclusive could just as easily be a 'consolation prize' for the 9 year track record they did have. That would be decidedly not 'petty' at all.
Similarly, the exclusive could be a test to see if he didn't go down the "Tim Cook derangement syndrome" hole again. His wrap around text to the initial news did not... but all of less than a week later of stewing on it and feedback from his circle ... and the whole marketing thing is Tim Cook's fault.
Finally, as I pointed out in
post 222 earlier. Apple did at least two sit down interviews during last year's WWDC 2024. Gruber's has a view count of 116K . Marquess Brownlee's has a view count of 3M . If the primarily point of doing these videos is to get incrementally deeper than the keynote discussion out to a broad set of end users, which one is the better option Apple should choose? Choosing 3M viewers over 120K is 'petty' ? Not even close.
Apple trying other possibilities in June 2024 happened way before November 2024. Likewise Apple doing something 10 years in a row would zero long term 'sanity' evaluation is also highly dubious.
