In theory, you could have gotten input from Microsoft, IBM, Mosaic, and so forth before ever releasing Javascript. Did you? No. Even assuming that those other companies had an insignificant share of the market, and could safely be ignored, you still could have asked for public commentary on your design, like you're asking Google to do now. Did you? No again. It's hypocritical to blast Google for doing the exact same things you did, for the exact same reasons.
Secondly, every attempt to create a "programming language for non-programmers" has resulted in something horrible. According to wikipedia, "one of the design goals of COBOL was that non-programmers—managers, supervisors, and users—could read and understand the code. This is why COBOL has an English-like syntax and structural elements." When you are comparing your language design decisions to those made by COBOL, it is time to give up.
Your own stated rationale for getting Javascript done in 10 days was to "prevent something worse" from happening. This is the exact same reason why Google is developing Dart. The only difference is that for them, "something worse" is Microsoft Silverlight, Adobe Flash, and Apple iPhone applications.
Right now, if I want an application that "feels native," Javascript is a no-go, and I have to use one of these (closed, proprietary) technologies. Shouldn't we be saluting Google for trying to make the situation better, rather than blasting them for not asking their competitors for a mother-may-I?
Dart is going to be an open platform that is well-supported by Chrome and Android. That alone should be enough to make it a viable choice. It's great that you created Javascript and that it became an open platform for everyone. Now someone is trying to build something even better. You should be helping them rather than raising objections which are illogical at best, and hypocritical at worst.
