If you don't like the Foundation show, that's fine, but this "oh, this is the hubris of Apple and I am glad they failed and everything they do is terrible and Tim Cook personally beat my cat to death" narrative isn't just tired, it's utterly irrelevant. What you don't like is David S. Goyer's take on Foundation. If you really don't like that take, then you wouldn't like it if it were running on Netflix or Amazon Prime or HBO Max, either, and it would have been just the same on one of those services -- albeit probably with a smaller special effects budget.
And the thing is, a "faithful translation" of the first books would be deathly boring. It's full of great ideas, but also full of flat characters, stilted dialogue, droning monologues, and very little in the way of actual plot. It's a story that hinges on the fall of a giant galactic empire yet lets that fall happen entirely off camera. One reviewer in 1982 described it this way:
> I kept waiting for something to happen, and nothing ever did. All three volumes, nearly a quarter of a million words, consisted of thoughts and conversation. No action. No physical suspense.
That "reviewer" was Isaac Asimov, when he re-read his own work before commencing the fourth book. Foundation started as a series of short stories patched together, then became a novel series full of retcons: it was all predicted by math! Wait, it was really the Second Foundation and Mentalics! Something something The Mule(tm)! Hold on, it was the robot from this other series entirely what the hell, Isaac!
Goyer has the disadvantage of trying to take what starts out as basically a future history sourcebook and turning it into a story, but the advantage of not having to retcon anything. There are already references to Foundation and Earth in the show.
Do I love the show? No, but I like the show. Is it turning a cerebral almost action-free book series into an action epic? Yes, but so far it's been a smart action epic, and I'm okay with that. Is it arguably Foundation fanfic? Maybe, but fanfic is usually "what if we shipped these two characters"; Foundation is fanfic of its source material in the sense of asking "what if Asimov created characters anyone would ever consider shipping in the first place."
