So upon further investigation, it turns out that this information was added by a (now perma-banned) lemmy user Amicchanwho lost access to their Prole-Wiki account and apparently the page for Common Software was deleted by CriticalResist (@CriticalResist8@lemmygrad.ml ?) due to the ban of Amicchan, and the Revolutionary Technological Commitee page was deleted by Forte, but the content and the broken link used as source for the section on Attempts on Replacing Free Software section remains.
And since I've seen many or the Lemmy-related software being licensed under the AGPL license, I guess the whole concept just collapsed. But I'd love it if the Wiki then adapted the page on FOSS to reflect the current choice to use AGPL right now.
