Ikon will probably change their pass structure next year, meaning adding passes with more restrictions, to solve some of these problems. The non-Alterra mountains may like to remain independent, but they see the future and the reality is that the number of visitors flying in was decreasing as Epic expanded into the Midwest unless they got on board with special deals (ie discounts for people with season passes at other resorts or some partnership pass). They also understand Mountain Collective will probably die, as Snowbasin/Sun Valley are going Epic and releasing a new pass next year with unlimited at both (and possibly limited days at other resorts) and Aspen/Squaw/Mammoth are going Ikon only. These mountains all have good relationships with Aspen/Alterra from Mountain Collectice and are therefore more willing to join Ikon as an add-on instead of going Epic. They may not like where the future is going, but from a business perspective, adapt or die.
