What direct executive decisions do we know for sure happened under his leadership that put Intel in the position they are in today. Not defending him. Just curious.
We can search the things we was heavily criticized for, but my TL;DR would be he failed to address the internal problems that were already obvious (for insiders, not us back then) and instead focused on "financial optimization" and chasing all kinds of other markets while the company's main business was already in decay.
IFS hit the wall under his leadership, the datacenter GPU failures did not help either. He was also overly concerned with his own financials, one could say almost to the detriment of the company: he got himself a pay rise while he was laying off ~11% of the workforce (12k jobs), and he mysteriously sold all the Intel shares legally allowed before Intel disclosed Spectre/Meltdown.
During his tenure Intel kept spending a lot on stock buybacks, something that unfortunately continued under Bob Swan as well. (this puts his Intel stock sell described above in a whole new light) We're talking tens of billions of dollars in total. Intel essentially destroyed their R&D and talent pool in favor of performing well on the stock market. Imagine the Intel of today with a war chest of 20-30 billion dollars, even in the form of diversified stakes in other companies. It boggles the mind if you consider both BK and Bob Swan knew that Intel was in trouble in terms of technological leadership, yet they continued to invest most of the company's profit in their own shares.
Remember Intel's attempt to enter the mobile market and the contra-revenue scheme that probably also cost Intel another 5-10 billion in total? Yup, it was him Imagine pumped billions to carve a place in the market
only to not have competitive products to follow up with.
There were probably other things I don't remember or can't find quickly enough. He was definitely not the only cause for Intel's downfall, but he worked hard to help the boulder reach critical mass.
