Nobody made that assertion. You made an assertion that standardization is "a pretty significant factor". You've yet to clarify what it's a significant factor in, nor have you provided evidence that it is, in fact, significant. I also didn't state that it's fine that Dart is proprietary, and I'd appreciate you not putting words in my mouth. My position is that your premise is incorrect and Dart is not proprietary.
