Well your dealership is conning more service from you, don't do it, your brake fluid should last as long as your car, unless the seal gets damaged, the amount of moisture that contaminates the fluid would be so minute, you can get a brake fluid tester online for $50 and it's the same tool the dealership should have, and that tells you the moisture content of the fluid.

No, a free firmware flash on pre 2015(?) fix that. I only had the sticky breaks a week before I went and had it flashed at a dealership.
Problem with bad break fluid is you can't tell you need a flush till your breaks fail in an emergency situation. You can buy a tester and use a different but compatible DOT that absorbs water less. I think DOT4 and DOT5.1 absorb water slower than DOT3.
