Sounds like this is a world wide problem and the idea of a company that does 'good' is nothing more than a CSR/PR play. Everything you have described can also be said for Google, Facebook and Amazon.
I don't know of many cooperatives that do "normal" business, but I don't see a reason why e.g. a cellular provider couldn't run on the same model, being perfectly aligned with their customers' interests, because the customers are also the owners. Mondragon Corporation in Spain comes to mind, but I have no idea whether they're friendly to smaller competitors.
Amazon is also not really famous for "bullying" its supply chain. We have heard such stories about Walmart and to some extent Apple, though you can argue that hard bargaining is not bullying and shouldn't be described that way. But Amazon has famously thin margins in retail. If they were really exploiting their suppliers so badly we'd expect to see fatter margins.
As for companies doing good, they do good every time they sell someone a useful product or service. More abstract conceptions of good are all problematic and often very biased.
