I had a point by point response, but I don’t think perpetuating this discussion is productive, so I’ll just leave you with the friendly advice that adopting a judgmental, nearly religious fundamentalist, and authoritarian approach to FOSS feels like it violates the spirit of FOSS itself and will likely be off-putting to even other FOSS enthusiasts, much less anyone you want to convince.
