The problem is that at the moment Intel only really have one business - selling CPUs for desktop/laptops and servers. In the latter market they are under severe pressure from AMD and Arm based CPUs. The former is relatively low growth.
They might want to have a third party foundry business but at the moment they don't have a credible one.
So they have massive historic and prospective capital investment and a cost base focused on difficult or uncertain markets.
Add to this poor recent execution and you have a toxic mix.
