Dye may have also been involved in that, given how unpopular he was internally at Apple. But more likely just personal / Meta offered him a billion dollars. Maestri leaving was also probably totally uninvolved.
Srouji is the weirdest case, and I'm hesitant to believe its even true just given its a rumor at this point. Its possible he was angry about being passed over for CEO, but realistically, it was always going to be Ternus, Williams, or Federighi. If Ternus is the next CEO, its likely we'll see Apple combine the Hardware Technologies and Hardware Engineering divisions, then have Srouji lead both of them. I really do not see him leaving the company.
The other less probable theory is that they actually picked Fadell, and this deeply pissed off many people in Apple's senior leadership. So, what we're seeing is more chaos than it first seems.
Generally, as long as Srouji doesn't leave, these changes feel positive for Apple, and especially if there's a CEO change in early 2026: This is what "the fifth generation of Apple Inc" looks like. I don't understand the mindset of people who complain about Apple's products and behavior over the past decade, then don't receive this news as directionally positive.
