Haha, had to ask as it's literally word for word what an ex-colleague of mine did on the job after we worked together. He worked for the only company servicing a particular type of machine in the country and decided he was going to run against them. He forgot that they were the only company who did it as they built the machines too and to maintain a warranty all their customers took out a service plan too so there was no actual real business for him, but they still chose to cease and desist him out of business too.

This doesn't have anything to do with machine repairs does it? Sounds extremely similar to something an ex-colleague of mine tried to do once.
