You must remember that all media is owned by someone. Roku doesn't own any of the content they provide via The Roku Channel, with the exception of a couple of things they've created themselves. So whoever owns the legal rights to "Then came Bronson" would have to offer it for rent (since that's all Roku does is rent the content for a specific period of time) and offer terms that are acceptable to Roku. A lot of times that content simply isn't made available for streaming, regardless of how strong the demand might be for it.
