Ask HN: What are the most virtuous companies?

So, in the past few days, this has come to my attention: companies suck. Har, har. Some companies purposely exploit their customers and clients (banks). Others have shady dealings with government and other interests (Dropbox, most of big tech?). Still others refuse to make money and instead loaf around on investor money (Quora, other startups with no revenue model). Most companies outside of tech treat their employees like crap. What are some companies for which you can't dig up any dirt? I still hold Mozilla up to this regard, as a company, but I can't think of any others. I don't want to set a hard minimum for size, so let's try to keep the discussion to relatively significant, notable firms.
