Inertia, layman brand perception, anticompetitive behavior (Intel has been in court for 15+ years about this).

An example in the laptop space, Intel invested a lot in the marketing and designs of the Ultrabook classification. So customers ask for an Ultrabook from Dell, Lenovo, HP, etc. and those are only available with Intel CPUs. It’s taken several years for AMD mobile CPUs to work their way into high end designs.
