Hulu is heavily shaped by the US market, so in practice its usefulness is most closely tied to US viewing needs and US availability. That is not a minor detail. It is one of the defining facts about the service, because so much of Hulu's appeal depends on current-TV relevance, bundles, and plan structures built for that market.
The reason this misconception survives is that Hulu does have a clear centre of gravity. Its strongest case is still US viewers who care about current TV, bundle options, or the ability to move up toward Live TV instead of just paying for one static on-demand catalogue, which is why people reduce it to a narrower stereotype than it really deserves.
