Context: I strongly dislike Facebook; I left years ago. I'm fairly interested in novel socialist, anarchist and resource-focused models for organisation as necessary improvements over current mixed mode we use in many countries currently (I just don't know any that will "work" at the required scale).
I don't think it's _that_ simple. Under capitalism, most systems are for-profit. Even governments and charities operate to raise capital to fund projects, so at the interface with people and most other organisations they have to operate similarly to capitalists (protectionism, hoarding, cost-cutting).
Because of this, you can't point to money-making as the only cause of the malpractice, without also implicating the person you're trying to convince.
