I think this may be the wrong question. I am the administrator of a reverse engineered PS3 video game server, so it’s illegal for me to make a profit or any kind of revenue or donations from that platform. However, I maintain it for thousands of users simply because I and others enjoy it and want it to exist. That’s not a sustainable model for a business or for running something as gigantic as reddit, but it’s what I want and enjoy, and for right now it’s affordable, and I’m happy with that.

It doesn’t have to be profitable. Especially for people that already have computers running 24/7 and good Internet, a Lenny server is just another process they run on their machine. Admin/mod duties would probably be the hardest part.

Lemmy isn’t profitable, and doesn’t plan to be. It’s not designed to be a moneymaking enterprise, it’s designed to be an decentralized community running on P2P open source software. If you work in the web development or IT industry full time, you likely have the skills to set up an Instance of your own for little or no cost, even of its just a side hobby on your personal computer.

Yes, in a way this means we are the equivalent one of those massive ‘miniature’ train sets that adult hobbiests play with in their garage.

The funny thing is that not all human endeavours actually need to be profitable for them to exist. It’s perfectly fine and normal for people to be generous and provide services for the community for nothing in return and for some of those in the community to help out too.

Lemmy has so far made $0 total profit. So that makes them substantially more profitable than Reddit.
