I wouldn't take the criticism to heart. The bit about bragging about how fast and small it is will always create friction - especially when another big library is needed to make it useful.
Also the result isn't as expressive as, say, Angular. You say that's a good thing:
"Current data-binding frameworks promote the use of spaghetti on the HTML layer. Suddenly the onclick attribute is back! (I'm looking at you, Angular)."
But you neglect to mention that the tradeoff is all the boilerplate you're going to have to write.
Also, you'll have to pry two-way data binding from my cold dead hands.... :)
