"They won't push back when bad decisions are made."
You have to define 'bad'. If you've drunk the kool-aid, you won't see decisions XYZ as 'bad', so there wouldn't be anything to push back on, even if they are objectively (or reasonably apparently) not good decisions.
"They will negotiate for more salary than equity/options, giving them less incentive to help make the company succeed."
Unless the 'equity' gives me the ability to actually change direction on patently stupid decisions and make course corrections, it's a lottery ticket. If a company is willing to pay me above market rate, I have far more immediate incentive to do what's necessary to keep that gravy train going, vs "hey, if we get sold for $100m, I might get $700k 3 years from now and be handcuffed for the next 2 years to some company who acquires us!!!" level of 'equity'.
If you do things well, it won't be a matter of 'believing' someplace is a good place to work, or they're doing good, or killing it, or whatever the metric is - it will just be factual, and won't require 'belief'.
