How it being an open source would help ad blocking on the client side? It certainly won't be as easy as current blocking methods for html/css/js.
You know it’s ok to say “I’ve made an emotional baseless assertion backed up with no evidence”.
I hate google as much as next person on HN, but at least have some evidence.
Not OP, and can't comment on Google's hidden intentions, but it does have a point - any such open source Flash replacements would make ad blocking harder.
