Whether or not you wear a mask or follow some other insignificant reg does not affect the pilot population as a group. If I am flying with you, I can choose to wear my mask if you don't. If I am a pax, I can choose not to ride with you.

When you choose to violate the law by working through a rest period and/or operating a flight without adequate rest, you put pressure on every other pilot whether they fly with you or not. The more pilots like you a certificate holder has, the more profit he puts in his pocket and the lower his rates get. Now his competitors have to push their pilots to break the law too in order to remain competitive. More pilots now have to choose between safe and legal operation, and a potential termination or lay-off (fewer positions due to reduced staffing levels). And so the cancer spreads.

Such a dilemma does not apply to the O2 situation. If I am a pilot who wishes to operate in a safe and legal manner while still remaining competitive, then I must educate you or come up with some other scheme to ensure that I do not have to make such a choice. If there is some other commonly violated reg that you feel affects you in a similar way, then I hope you will feel free to educate me (in another thread, please).

Spreading the word is probably the best thing you can do. Eventually every pilot is going to have a bad day, get fed-up, and use this. Certificate holders will ultimately have to staff or schedule appropriately in order to maintain reliability.
