It's irrelevant. Those shows could have been put on Netflix. The is no need to continue to segment the streaming market when there was already a service you could put your shows on.
Not true at all. I am sure many of these shows, if not released on TV+, would have had either lower budget, lower quality, would've been canceled before reaching a 5th season, or wouldn't have been made entirely.
Netflix has so much clutter and garbage, that some of the truly great shows get obscured, like The OA or Santa Clarita (which got canceled too early, among many others).
Apple has spared no expense in the price tag of these shows. Just look at the cast in Morning Show, the cinematography in See, and the incredible period recreation of For All Mankind. And that's only the launch titles.
Other shows like Dickinson or Little America very likely wouldn't have seen the light of day on other services due to the out of the box nature (yet these two are both incredible shows).
There are SO many pilots which are made and then passed over because they don't fit what the streaming service imagines the customers want. I am certain Ted Lasso would not have turned out as legendary had it not been for the freedom and trust that Apple gave its producers.
Apple has the deep pockets to make TV+ a success and ensure a steady stream of high quality content, sparing NO expense. Especially at this early juncture where Apple needs to prove itself, the quality output will continue to be incredible. And I expect at least 5 seasons of the flagship series (Dickinson, Servant, For All Mankind, Morning Show, See, Ted Lasso, Mythic Quest).
