Yeah, but what on earth is the alternative?
Mobile gui's without javascript would be horrendous. On top of that, that's the platform you're minifying for.
I don't minify javascript to hide what's running, I minify it because a 3KB file is a lot less to download than a 12KB file.
So what? You design an entirely new language that: A) Can't be minified (How?) B) Has to be open source C) Can't be obfuscated (virtually impossible to prevent)
I'm sorry, but the stance is kinda dumb.
