While they are deliberately blocking Youtube nationally, I suspect the wider issue has no malice, and is a case of poorly constructed/ implemented outbound policies on their part, and poorly constructed/ implemented inbound polices on their upstreams part.

They probably have that /24 going to a gateway walled garden box which replies with a site saying 'we have banned this', and that /24 route is leaking outside of their AS via PCCW due to dodgy filters/communities.
