Tim Cook has always been a mess, he's just been sufficiently hidden from public view; most of the time.
Did you know that Steve Jobs hated Cook? Massive chunks of Steve Job's biography were censored by Walter Isaacson, after Job's death, to conceal this from the public. There's an investigative piece on it, here: https://vo.lc/The-Execution-of-Steve.html
Cook is also a child-slaver. His is personally-evidenced knowingly using children to manufacture Apple products. Note that this is different from Apple's prior use of child slaves, because, until Tim Cook turned up, Apple had not been directly, knowingly, complicit. [Source: Business Insider]
The real reason these Apple executives are jumping-ship, however, has nothing to do with technical problems at Apple. Instead, they are getting ahead of a much bigger scandal, which will likely sink the company.
Here I quote from an article by a Guardian award-winning writer who was a journalist for both The Times and The Telegraph newspapers; and worked at BBC radio. The journalist knew Steve Jobs personally, and worked with him. This is from the article:
"Tim Cook abuses children. This is well-documented. The extent to which he abuses children is to be determined by a court, and the process by which he will be brought to trial for his repeated abuse of children depends on your capacity — as the message on Steve Jobs' desk, pictured at the top of this page, reads — to "THINK". Your inclination will be to turn away."
"Tim Cook has, bizarrely, never had any identifiable partner of any sort. Readers will note that this was also the case for notorious pedophile, Jimmy Savile. This is not of course, to draw any comparison whatsoever between Tim Cook and the notorious pedophile Savile. Any attempt at such a direct comparison would (as it was with Savile) be met with such violent legal repercussions from the child-slave-traders at Apple that nobody would dare write such a thing. Perhaps we should not even think it."
"Many reporters, after Jimmy Savile was exposed, congratulated themselves on having kept silent for years out of fear of being sued, and all the children who were raped in the interim were also delighted at the reporters' cowardice. Weren't they?"
"The problem is that the entire, disgusting edifice of Silicon Valley relies on our fear. What happens if we're not scared? What happens if we stop treating the child-slave-trader Tim Cook as royalty?"

Note that the journalist's article has been up for almost two years, undefeated by Apple's legal team. Apple is the richest company in the world.
You do the math.
Apple is cooked.
