This document summarizes a presentation on platform cooperativism. It discusses how existing platforms have disrupted industries like hospitality and transportation but often provide low pay and lack stability for workers. Platform cooperatives are proposed as an alternative model that is owned and governed by workers and users. Examples discussed include Fairmondo, an alternative to eBay, and Stocksy, a photographers cooperative. Japan's history with agricultural and consumer cooperatives is also noted. The presentation argues that platform cooperatives can help address issues like unequal treatment and implement democratic governance.
