I don't know what the case is for Indonesia, but I seem to remember Tubi once being available in some EU member countries, but when GDPR went into effect, it (and probably some of the similar services) had to cease offering service there--at least until they could figure out how to change things without hemorrhaging money--or they would've been in violation of the new laws. Maybe something similar was the case where you are?

Not sure if there are any new laws that stopped Tubi from offering their services here, but even if it does, it doesn't make the headlines. Most people here don't use Tubi anyway.

One possible scenario is our overreactive censoring. Like Vimeo and Reddit for example, those sites have nudity, even though its more of a site that allows it rather than being a full-on NSFW site both are still blocked. I heard Tubi has lots of low-budget movies that capitalize on gore and nudity, but I think its not the case since the web is accessible unlike those 2.

Yeah, that had crossed my mind as a possibility. Tubi definitely seems to have somewhat more permissive attitudes toward content than some of the other services like The Roku Channel seem to. I could definitely see Tubi being a service that conservatives (or anyone else) who don't like sex and/or nudity and/or violence in media might target for censorship--or just a blackout.
