I'm always amazed when I find a project that is still using Sourceforge. I always assume that it is completely unused by any active projects anymore. MX Linux was the most recent one I came across. Their ISOs are on sourceforge, although they use Github for their main repo.

And...apparently Sourceforge was bough by Slashdot in 2019?! Wow. Two early-2000s heavyweights right there.
