This is a devops tool named Terraform, nothing to do with terraforming.
Like Aerospike, or Uber.
McDonald's was at least started by two guys with the surname McDonald. It is/was their company so they named it after themselves. That's no different than "Frank's Burger Stand", which is again completely different than writing a clone of GCC in javascript and then calling it Patriot or something.
(this isn't to say it shouldn't have had a better title - but just to explain why a lot of people weren't bothered by it)
