What ruined Apple was not growth but values: executives who cared more about their own glory and wealth than about making great computers for people to use.

What ruined Apple wasn't growth. What ruined Apple was values. John Sculley ruined Apple and he ruined it by bringing a set of values to the top of Apple which were corrupt and corrupted some of the top people who were there, drove out some of the ones who were not corruptible, and brought in more corrupt ones and paid themselves collectively tens of millions of dollars and cared more about their own glory and wealth than they did about what built Apple in the first place--which was making great computers for people to use.
