It was in all probability,an executive decision made by the company and not the pilot(s).
the PIC ... took this decision in about 20 minutes...
Sounds about right. A diversion decision is not made only upon, as someone else said "Land ASAP". And one of the PIC's responsibilities is to save money for the company; how does he do that? Not diverting to an airport which is not served by the company, and the statements above made by others are dead on-spot, much more "comfort" possibilities for the pax, the engine change...
