I suspect the implication was that being written in Python makes the code more accessible to "normal" people, both to read and (perhaps to an even greater extent) to run. If it were written on .NET one would likely (because Mono is incomplete) need a Windows server to run the code. If it was written using Java there is a decent chance it would require some pretty complex configuration and possibly a license of some sort from Oracle. I might be misinterpreting the comment, but when I personally poke fun at Java or .NET for being "enterprise-y", this is more or less what I'm talking about.
Actually though, it's rather difficult to run into Mono incompleteness when making a web app these days. Mono's mostly lacking Windows-specific stuff like WPF (UI-framework). Used to lack Entity Framework but that's solved since MS open sourced that. You can take an existing ASP.NET app and there's a very high chance you can just build it with xbuild and host it with Mono's xsp server.
More generally, I do see your point but I believe it's a little outdated; the time that Java apps just had to be built on 200k lines of XML is long gone as well.
It's obviously a matter of taste, but I find it difficult to accept that well-written Python would be easier to read than well-written C#. C# is more verbose in places and less verbose in others. Writing crap code is about as easy in both.
Are there really places where C# is less verbose by any significant margin? The only thing I can think of is that a well-written LINQ library lets you abstract away a tremendous amount of heavy lifting into a clean and declarative query, but other than that pretty much everything requires more keywords, punctuation and declaration in C#.
Don't get me wrong, C# is relatively explicit and regular, which does wonders for its readability especially in large projects with many collaborators. But brevity is not one of its strong suits, nor should it be.
Indeed, lamdas and LINQ. The moment you're using functional primitives that don't fit in Python's list comprehensions well, C# becomes a lot less verbose, and certainly less obtuse.
