Why bother claiming a connection to source material you hate?
I don't think the source material is hated. There are plenty of articles that go into the thought process of making the series.

"To say Apple TV+'s
Foundation diverges from its source material would be a bit of an understatement.
An adaptation of Isaac Asimov's classic science fiction novels,
Foundation is less interested in following its source material to the letter than it is in creating a story within Asimov's universe that would make good TV. The basic plot remains the same: mathematician Hari Seldon (Jared Harris) foretells the fall of the Galactic Empire thanks to his theory of psychohistory. Knowing the fall is inevitable, he establishes the Foundation in order to preserve knowledge and, hopefully, civilization in the years to come..."
Just the first 2 paragraphs or so might be worth reading from
In 'Foundation,' now on Apple TV+, the 'Mad Men' and 'The Crown' veteran conveys something elemental about his character — without even standing up.

from the article. "...it’s a book often called “unfilmable.” Having read it, I would say that this is not so much because it is too stylistically complex as that it — as written — is not worth filming. About 90% talk and maybe 3% action, it was inspired by Edward Gibbon’s “The History of the Decline and Fall of the Roman Empire,” and is almost as dry — less a space opera than a salute to diplomacy, brinksmanship and the stratagem that cuts conflict off at the pass...In any case, series creators David S. Goyer (“Blade,” “
Man of Steel”) and Josh Friedman (“
The Black Dahlia,” “Avatar 2") did something else here, creating scenes and relationships to make “Foundation” more conventionally dramatic and exciting and politically contemporary. Many male roles have been gender-swapped — not hard to do when your characters have names like Lors Avakim and Salvor Hardin, and a welcome improvement on a text that is pretty much wall to wall dudes, and pretty sexist whenever a woman peeks in. Some scenes seem written almost just to justify the special effects, which are, indeed, special."
I have never read the books that make up Foundation so I have no complaints about the show. Maybe one day others will try to make the source material a movie or two. I'm hoping others will try to make War & Peace, a movie because it is a fabulous book.
