Here's how it works on sourcehut:
You pay us the subscription fee of your choice and you get access to our services. We spend it on maintaining and upgrading the hardware, and paying for staff to handle development, operations, support, and on-call.
Because we don't take money from investors, we're only accountable to users, and if we aren't working in your interests, we lose our revenue. We are incentivized to work for you, not to generate a return.
Because we're running 100% free software, we're held accountable because anyone can take our shit and run it on their own servers, or even bootstrap a competing company using our own software. We've made it easy to run out out of business if we lose your trust.
