My understanding is they do it to get more coffee out of the grounds so they use less coffee grounds to maximize profits which also increases the risk of cause esophageal cancer.

My personal preference to accomplish maximizing coffee extraction is to use extra filters and less coffee grounds but that takes longer which may not be a viable option for that type of business.

I don't think this is a relevant factor. According to one source [1], the optimum brewing temperature is "around 198-202ºF". That's only around 10F away from boiling. I'm not sure how much difference that would make in terms of burning. Keep in mind that something that's hot also cools faster, so by the time it ends up being served, the difference is likely much less than 10F
