Spoke with some guys at higher management level, and the word of the day is "enforced fluctuation". They are trying to let branches they no longer want die out with only the brightest still maintaining what is left of them while bringing in new people to build up new areas.
Want proof? They are actually hiring new people for IoT and automotive in the middle of ACT. Practically no internal recruitment happened for automotive even though they are hiring several hundred people there.
Intel simply has no interest in developing internal people. The Intel development plan is to get rid of low/average performers and to bring in bright people that were developed by other companies. ACT was only the first step in that direction. There are more severance programs coming in 2017. HR is already preparing for it which is one reason why quite a few HR people have left the company recently - they are not willing to support this anymore.
