Are the nonprofit projects still a thing?

I am having trouble locating where to sign up for a nonprofit project, not sure if they still exist? Also noticed several 404 links when doing a search for them.

Maybe I am missing something, would appreciate any clarification.

Instead of connecting people to non profit organisations, freecodecamp is creating open source softwares that all non profit can use:

You can also contribute to FreeCodeCamp itself:
