Because it's Policy. Many years ago, we deleted all YouTube videos as per that Wilders' policy. Then, after much discussion years later, we started to allow de-lnked YT videos, reserving the right to remove videos that did not meet our Terms of Service, thus why the policy's language remains unchanged. There have been instances that we have de-linked web sites and web pages or removed them all together (as per our TOS), depending on the subject matter. We depend on members reporting such instances, and objectionable content are either edited or removed as per our TOS.
