Out of the comments defending GoJet, nobody has disputed that they've fired pilots who put in a full two week notice.
As for who has better MX, actually there are metrics, just like D0 and A14. Plus I'm sure that whoever is inputting delay codes fudges the numbers in favor of their regional of choice. So yes there is quantitative evidence that GoJet MX is worse than other regionals.
As for the history, you're correct that a vast majority now are not associated with how the airline was started, but GoJet and TSH management have a pattern poor choices.
Refresh my memory as to how the launch of IOCC went and how happy Delta was?
