Just had my son go to the dealer for an oil change and the say the brake fluid was dirty and had moisture in it. Is this normal?

Maybe - depends on environment and age of car. Fluid change is recommended maintenance at 3 yr/ 36k miles whichever occurs first. Being in a high salt environment it's preferable to a seized caliper. I'd also have them clean and lube the caliper slides to keep corrosion at bay.

My maintenance minder popped up for brake fluid change at 22k. Just flushed it last weekend. It was...a bit cloudy and there were definitely particulates in the bottom of the bottle when done. Simple process. I recommend doing it.

Brake fluid is hygroscopic which simply means it absorbs moisture from the air. It will always find a way to absorb moisture which will degrade it. It's good practice to change your brake fluid every couple years as preventative maintenance.

I don't drive much, and I'm in So Cal where the weather is mild, so I changed the brake fluid at 25k, which was about 5 years. Coincidentally, the maintenance minder popped on right after the job was finished.
