It also sounds from PR that despite taking control of Hulu, Disney also has interest in Hulu remaining their Live TV offering for non-Disney channels, and that Disney would still like Hulu to be a welcome home for what Time Warner and NBC Universal content it can continue to license, though that will probably start to get weird in coming years. It probably would still be in Disney's interests that Hulu seem a "neutral" or "cable" brand, especially given the actual cable infrastructure that AT&T (Time Warner) and Comcast (NBC Universal) directly control.
If money is speech, Disney has been talking a lot in how much money it has spent on both the Disney+ project and the Hulu buyout. But speech of the money will always be a bit of reading the tea leaves and the color of the wind.
Hulu is also only a US domestic service. Disney surely wants to sell subscriptions to its more mature material worldwide, just like Disney+.
Also, Disney seems to have renewed Hulu's exclusive contracts for Cloak & Dagger and The Runaways, so it sounds like Disney is very prepared to take a "split" approach to Marvel with Hulu being home to an interesting subset of Marvel properties. It does sound like R-rated films like Deadpool will be on Hulu rather than Disney+, at least based on conjecture so far.
(I also wouldn't be surprised if all of the Fox X-Men stuff ended up at Hulu rather than Disney+, rather than confuse young fans of the current MCU. It may be Disney makes the dividing line be the "Marvel Studios" brand, of which the Fox films were not. But of course that remains to be seen.)
