It's the general difference between full-time broadcasters and streaming subsidiaries of companies like Apple, Amazon, or Google. A broadcaster may decide to focus on a particular segment of the audience at the risk of alienating others.
A company like Amazon, Apple, or Google, on the other hand, ideally wants to do business with as many people as possible and treats its streaming offerings as a way of attracting new customers. Anything that could be considered controversial or drive away customers is considered bad for the overall business. It's the video equivalent of the inoffensive, lowest-common-denominator hit radio programming that took over the airwaves in the 1990s.
