That's every company, most upper management don't stay in one position for more than 2 years. So the system is setup for short term gains because investors aren't interested in long term investments and the blowback is the next guys problem. Who then is looking for the next big win to cover up the last guy issues without fixing anything. Then they bring in someone to clean up the mess and the cycle starts again.

Plus most consumers have short memories or don't have an alternative so their stuck. There are small groups holding on but for 75% of the world's population right now it's Android or iOS, AMD or Intel, AMD or NVIDIA, Samsung or WD or Seagate or SanDisk, Att or Verizon, Apple or Microsoft, and so on.
