It could be suggested there's a connection between Bosch: Legacy's cancelation and Freevee's shutdown.

Amazon is officially shutting down Freevee, its free, ad-supported video streaming service originally launched under the IMDb brand.

Amazon is going to shut down Freevee, its free ad-supported streaming television (FAST) service. The service’s content has already been migrated over to Prime Video and new episodes of Freevee shows will be available to people who don’t pay for Prime, Deadline reports. The brand will be phased out “over the coming weeks,” Deadline says.
