Because if there are software projects that can't practically be free software while bringing in enough money to fund development, then free-software advocates should acknowledge that sometimes proprietary software is a perfectly valid option. Put another way, while free software is good and should be encouraged when it's practical, I don't think it's right to insist that proprietary software is bad and should always be avoided. The companies that abuse the power that comes with the proprietary model are well-known (and thankfully I no longer work for one of them). But some developers of proprietary software are just trying to develop good software while making a living, the only way they've judged that they can. Also, the hosting business model sometimes leads to misaligned incentives. I don't believe Sourcehut falls in this category. But consider, if a developer of an open-source package makes their money from hosting, then what incentive is there to make the package easy to self-host?
