So many red flags in here.

First, the CEO is an idiot for publicly saying that. This is most likely alienating 20% of the company.

Second, pushing back on stupid ideas is good, but being aggressive and offensive is not. Knowing how to rally people is a critical skill to master. You can be the best technical dev in the world, if you behave like a dick and nobody wants to work with you you won't get far.

Stop working during weekends. All you're doing is normalizing what should be very exceptional.

Finally, the fact that you can't talk to your boss about it is really messed up. It is a clear signal that you need to GTFO.
