When IMDB was sold, it was seen as if wikipedia was sold to a private company. Amazon promised to leave IMDB mostly alone, and to provide data feeds / db backups for free. They are still available although new features of IMDb have not been migrated to the original datasets.
It's a pity keywords aren't in those datasets. Still, it's nice that this still exists. https://developer.imdb.com/non-commercial-datasets/
