I wrote an article back in 2020 warning against relying on privately owned platforms for creating communities and public forums. These companies are not accountable to the users, and they curate the content on the platforms in opaque ways that ultimately serve the interests of the owners of these companies. The same Marxist argument about workers owning their tools applies to digital platforms as well. We have to have software that's developed in the open, and that's hosted by volunteers, and funded directly by the community. This is the only way to ensure that our interests are represented.
