Usually it’s because they have a distribution deal with a local TV station in that country where the deal prohibits them from distributing it themselves. The local station wants you to watch it on their own streaming service.

This is why when when CDs originally came out, the industry kept saying “soon CDs will be super cheap since they’re so much cheaper than manufacturing tapes!” (which really DO need to be dubbed linearly, even though they can be done at like 10x speed in digital high-speed dubbers) before they realized people were still perfectly happy paying $15 for a disc.
This is also why they kept trying to make laserdisc (and RCA’s CED) be a thing, since they were cheaper to mass manufacture by stamping than prerecorded video tape’s slow dubbing process. It was thought that prerecorded video tapes were always going to be too expensive (originally they were like $100 a tape, hence the rise of video rental stores)
