Noshareholder would be more honest.
This is said knowing nothing about the company in question, just from my own experience working for a non-profit. Employees still need to be paid.
That is literally what the OP is arguing that people who found non-profit organization shouldn't be paid even a modest salary for their work.
This raises some interesting questions. Would you expect to see people in charge of this org, performing the day-to-day jobs, to work without receiving any pay? When you say the people are profiting, do you mean the organization is receiving more money each year than they are spending? That is certainly the goal of all orgs, businesses, churches, soup kitchens, and government NGO's.
It's an interesting question. I suppose they could take on jobs elsewhere in the private sector, and then perform these jobs for Hack Club at zero cost to the company. I would say it comes down to time spent. How big is Hack Club? If it can be managed for 10 minutes worth of work a day, then perhaps that should be donated time. If it requires more than 8+ hours a day. And if the work is specialized then it def needs the right person there, WITH the expertise to run this company --- then they should receive pay for his/her work.
