I am looking for a website similar to Privacytools, Prism Break, Ethical.net or switching.software but more focused on freedom than privacy, presenting the best replacements for proprietary programs in the desktop and mobile. Is there anything like that?
Try FSF and FSFE for free software recommendations. And searching for specific software categories and adding “open source”. Generally works fine for me. Also, a good site to find FOSS alternatives to software is: https://alternativeto.net/
