Brake fluid is hygroscopic - it absorbs water. Over time this will reach a point where the water builds to the point where it will begin to oxidize the metal in the brake system; this leads to expensive repairs or possibly sudden failure. It is cheaper to change the fluid.
I've not worked as a mechanic for about 30 years. The only excuse I can come up with for a hydraulic system flush is water contamination or other fouling. Not something I'd expect in a sealed system with healthy components. Could be there is some form of chemical breakdown over time with whatever they are using for the fluid. No idea.

That is true if you are using what in the US is called DOT 3 or 4 brake fluid.......Newer vehicles use DOT 5 fluid which is silicone based and non-hydroscopic. I know this from my motorcycle days as we used DOT 5 because it also has a higher boiling point.....important under the high brake temps generated in racing.
