That's because the "science" on firefighting has already been settled. They know exactly what will happen when you do X to a fire and they know how to stop it fast and efficiently. They know what the consequences of spraying water on a fire are and when you won't be able to put one out etc.
It's quite different to run in and say we need to mask, lockdown, close businesses/schools, produce a vaccine and distribute it immediately. Ok why? Are you sure this will save lives? They had no idea, it was just a knee jerk reaction. You can partially justify these things when they didn't know how bad COVID was going to be but then they continued with them for 2 years with very little evidence to back up their decisions. At some point you have to back off and say "hey we don't have a damn clue what the best course of action is". If your fix is worse than the problem you might need to re-evaluate and wait for the actual science on it.
I think people make the assumption that you HAVE to do something immediately when bad things happen, sometimes doing nothing and observing is the better option. There are multiple examples of the choice to do something being worse than doing nothing during this pandemic (e.g. governor sends infected persons into nursing homes) and as time goes on I think we're going to see more fallout from some of these choices.
