Earlier quoted context omitted.
What do you suggest? If you intend on redefining it in a way that takes away property rights, then I won't support it and neither should you.
How about a trade-off, something like: In order to receive "Safe harbour" copyright immunity for uploaded user content, you have to have fairly lax rules on content (e.g. only blocking actual criminal content, which is all youtube have done before this, right?). If you want to significantly curate your content, you can't hide behind the legal protection of "uncurated user content".
Is YouTube gaining some benefit from pretending to be an open platform? I'm not sure what you're saying here.
Likewise, isn't copyright infringement is a criminal offense?
