That's fine - you are entitled to do what you like within the law to make your point s long as you are willing to accept the consequences
BUT - how many people affected will ever fly Spirit again? They don't sympathise with the pilots - all they know is "the airline" screwed up their travel
Eventually Spirit will suffer and may well go bust - that actually doesn't affect the passengers (or customers) and you can bet the managers have already covered themelves - who will suffer? The employees who will be out of a job....
