I think most of you are missing this one section of Joe's letter:
despite having taken federal Payroll Support Program relief that allowed it to maintain its workforce during the pandemic and even grow its pilot ranks by nearly 9 percent in the past two years. Moreover, SkyWest Airlines announced it would drop its EAS service to the 29 small and rural communities while at the same time applying to the government for other EAS flying.
I think the above statements are correct that they just want to move the planes to something that might be more profitable. I hope the DOT holds them to the contracts that they signed.
