Your link is broken, below is the correct one. More importantly, Intel wants AMD to stay alive and keep vaguely competing with them since they avoid significantly worse anti-trust rulings in the future (here is a current one[1]) due to there being no active x86-64 competitors.
Additionally, think about Google, Amazon, MS Azure and all the other big players who push large volume on Intel's higher end SKUs, what do you think they will do if Intel becomes their sole source vendor? I'd predict all 3 will take their current dabbling in ARM servers and amp it up, since being captured by a single vendor is a serious issue for all of them.
