Because nothing else works as well for *most* brake systems, and it is also great to have around for lubricating plastic, plastic on metal, and conditioning rubber (like window moldings, but wipe excess off so it doesn't become a dust magnet) or lubing urethane suspension bushings.
It's also superior to anti-seize goop for use on wheels that get rusted on the hubs, providing you don't use an excessive amount. I mean on the wheel interface to hub center, not the lug nuts. Do not grease lug nut studs, you'll end up playing a guessing game what the torque derating should be and then risk them coming loose easier.
I'm not suggesting you can't use anti-seize, or use other greases for caliper pins, but the main reason people use something else is other choices are cheaper and back in the day, few knew to use silicone grease instead of something cheap marketed as brake grease due to putting metal or ceramic in it to deal with the heat when the base grease was relatively poor at it by itself.
