There is also an argument that web services should not force you to pay after already pulling you in for free (unless it's explicitly a trial). Obviously this doesn't account for people using a service for free due to a hack of some kind, but there is also an argument that adblocking is not a hack - rather, that it is a "working as intended" feature of the web, and is simply a habit of a subset of the viewerbase, and, crucially, that this is known to YouTube, who chose of their own free will to explicitly allow it for many, many years.
