There's no questioning that a deep sand bed or plenum does a really good job at removing nitrates, the science behind it is pretty well understood. Where people run into problem is actually getting the thing to work right, too many people end up with it turning into a nutrient slough.
I'm not sure there is an easy answer answer to getting it working either. You have to have the right amount of critters working to keep it clean but you can have too much of them as well. Sometimes putting something like a cucumber or sand star in there just results in having all the bacteria you are trying to keep going eaten and you end up with a crash eventually. It's a delicate balancing act.

And needs to be seeded and maintained.
I think people get lazy and a bit bored after a number of years. They don't do as many water changes as they used to because the tank is running great after a few years. Then the first place you will have problems will be your DSB. So the problem is blamed there but in reality it is the husbandry of the tank that is the real problem.  My 2 cents. I can't comment on running BB as I have always had sand. I just can't see how you would keep some fish happy without sand.
