The Sourceforge UI and overall experience is still a decade or more behind the experience on GitHub and most of the other modern and maintained equivalent sites/services like Fossil, GitLab, Gitea, etc

That ancient feeling UI doesn’t win them a lot of forgiveness, if the only notable change has been “we took away the malware” and the site continues to remain stagnant, SourceForge will continue to feel very inferior to more modern alternatives.
