Everyone wants fairness and equity until the time comes for each to pay for it.
I'm saying this in a disappointed tone as I really would like platform cooperatives to work but they're going to fail to compete in a relatively open market of a capitalist society. Also, everyone working in IT for these platforms becomes the exploited. It's inverted exploitation. Programmer: you're being paid less than what you'd make in a free market. If you're not getting your flat cleaned twice a week as a member of this cooperative, you're doing it wrong. You, my friend, are being taken to the proverbial cleaners.
