From an anarchist perspective, nearly every company is evil to some degree. I did consider trying to avoid the supremely evil companies such as the fossil fuel industry, arms industry, mercenaries, private intelligence companies, factory animal farming, etc. But it'd require a lot of labor on my part which I can't perform and it doesn't seem like it'd have an impact when it comes to ETFs anyways.

I might look into ESG investing but my assumption is that it'll be a bunch of liberal whitewashing. I do wonder if people could develop some sort of community-focused investing which prioritizes worker cooperatives which produce a somewhat ethical product?
