Free Software (Proprietary Software Replacements)

I found a page on this several days ago and cannot find it now...

I thought it was on fsf.org.
It gave examples of free software next to proprietary software.
It was not: https://directory.fsf.org/wiki/Free_Software_Directory:Free_software_replacements, however, that is similar to what I remember seeing.

Does anyone know what I'm talking about?
