I'm not sure where you'd get the idea that Codefloe is for people who don't want FOSS. There are hundreds of open source repos. There are also a lot of personal projects, and probably some commercial ones as well.
What they don't want, is an ideology that restricts the types of projects hosted there. Its available for all software projects. Most of their user base are just using the service - and that is really the point. Similar to how most users on Lichess are there to play chess, not to talk about hosting chess servers.
They are owned by a commercial entity, devXY but they are not profit seeking. They need donations to cover costs but are willing to give that time to build up. There are some regular donors[1], but they are not yet covering all costs [2].
They publish a report every quarter where you can see usage figures.

They also publish detailed cost analytics and donations:
