> not a single large company with a good culture and good business metrics

There are plenty of mega-companies that are very, very different and very, very successful. Koch Industries is a good example. Do they manage with a Silicon Valley ethos?

There's a perfectly reasonable explanation as to why there are not other companies in tech who rival these ones, and that's mentioned in my very first post: the consumer software industry naturally lends itself to monopolization, which we also know observationally has been happening.
