Really? You have friends in almost all big companies?
There's a lot of truth in the points you mention, but even in my limited experience (six years at two companies, one very large and one pretty small), it's much more complex than you suggest. Many of these things were flat out not the case at both companies (e.g., the points about "the world outside"), some of them were absolutely true of both (2-3 hours of coding per day is common), and some were worse at the small company (e.g., documentation).
I'm with the parent: these issues have little to do with company size, but they do reflect the quality of an organization. In both environments I've worked in, to the extent that these issues were present, they were considered problems to be fixed, not something to be resigned about.
Also there aren't that many tech companies as big as Microsoft, in terms of either market cap or number of employees. Seems pretty easy to have friends at all of them if you were friends with a lot of people in a CS department at college.
But that undermines the original point about big companies even more. Having friends at mostly big companies is not only not enough to generalize about big companies, but it provides no information about whether other companies struggle with these issues too.
