We agree on Java the language being mismanaged. Especially in comparison to C# (see a recent InfoQ interview with Neil Gafter). But the JVM is in better shape.
I despair of your reading comprehension, though, when it comes to what I have written about the leaked memo's Dash strategy. I never wrote that JS can be as fast at Dart-to-JS code as a native Dart VM could be. Not ever -- quite the reverse.
Now if we on TC39 had the benefit of Google's Dart expert input any time in the last year, we could have possibly worked harder on guards (optional type annotations), branding (aka trademarking, nominal types for use with guards), bignums, classes, or other proposals that have suffered in comparison to those that clearly made it into ES6. FYI, these were all strawman-status on http://wiki.ecmascript.org over the last year or so.
Some Googlers on TC39 did work on a few of these, in most cases too late for our agreed-upon ES6 proposal cut-off date. We did hear a dire warning from one Google rep in May 2010 that if two of these proposals were not promoted to Harmony status, JS "would be replaced!"
So your complaints about the ECMA standard not progressing fast enough come with ill grace from a google employee. Google has a lot of power and it has not discharged it responsibly, in my view. ES6 would be a better Dart-to-JS target language, including draft specs and prototypes in V8, if it had made a concerted effort.
Contrast this with Mark Miller (Google) and Tom Van Cutsem working in the open, and very effectively, on ES6 proxies, already prototyped in SpiderMonkey and V8. Or the module system designed by Dave Herman and Sam Tobin-Hochstadt in the open, which you overlooked.
Talk about self-fulfilling prophecy! In this case, you are not even predicting the future, you're misstating the past.
I think if it wants to be taken seriously as a good force in advancement of the web, google does have to be aboveboard with its involvement in TC39 and put in significant effort there. Maybe they really should have put in more effort to pushing strawmen through (I wasn't paying enough attention a year ago to comment on that).
But are you suggesting that particular people at google should have been (forced to be?) more involved in TC39 efforts? I don't think you can force that (and someone like Lars Bak would probably just leave if he didn't want to do it). There are lots of language experts out there that are working on their pet compiler instead of helping with the next coffeescript variant. That's not an evil, it's just a missed opportunity (and the reality of trying to get good people involved with a standards process).
I think that your better argument is that an open Dart repository from the start could have fed ideas back into TC39 process, but the problems you mention didn't suffer from lack of knowledge about them, just champions for strawman solutions. That is, again, not a job that most relish.

"Unnamed sources at Google suggest gmail actually runs on the blood of orphans, kittens." What are you, a Techcrunch guest columnist? Give a name or don't bring it up.
You seem scandalized by the idea that an employer might force employees to work on standards (or anything else per typical work-for-hire contracts).
That is not unusual. It's dog-bites-man.
What's going on is unusual, in my experience.
Google is forcing people it employs off of tc39 work. I will not say whom, since I was told in confidence. Three people at least. This casts a different light on the Dash memo's serve-two-masters glibness, and on Alex Russell's recent blog post.
