If you find yourself concerned about whether a company aligns with the philosophy of a previous CEO, while not being an employee or investor of that company, then you might not realize the extent to which your mind has already been captured by their marketing efforts.

You don't need to care about Apple's (or Google's, or Samsung's) "philosophy" about literally anything.

This makes sense if the previous CEO is a regular "Joe the CEO". If that previous CEO had a very rare talent of designing or building great products, losing it is a concern.
