They should absolutely be for profit. How else would the skills and information needed be obtained and maintained? Doing these things is not cheap! Just tooling can surprise one thinking about this activity. In fact, the more for profit repair centers there are, the better. Back when things came with some expectation about service, one could find shops all over the place able to do services. I learned a lot about how to repair and setup CRT Televisions from one back in the 70's when... I WAS A 6TH GRADER IN PRIMARY SCHOOL! No joke. The shop was right across the street. Before high school I was reflowing circuits and boards, testing and replacing tubes, other components and could do a basic bring up on a new CRT. Skills I used in high school for date money. It is crazy how far away from that we have come.
