If the voice of an author can be heard through their writing, the act of reading can be affected by one's understanding of the author. "Death of the author" may be a useful critical technique but it's not the way most people emotionally or intellectually connect with art.
Having known this about Asimov for quite some time, it hasn't kept me from enjoying that of his work I really like, but it has somewhat dulled my enjoyment of him overall as an author. In particular, although it's never been a favorite of mine anyway, I can't see myself being able to avoid noticing that _Foundation's Edge_ has a plotline that pairs off a middle-aged professor with a young, pretty, sexually open-minded woman who is "bottom heavy".
I really enjoy the concepts in H.P. Lovecraft's mythos, particularly where horror intersects with science fiction, but I also enjoy it a lot less after learning about his rabid antisemitic and racist views[0], which were extreme even for the time.
I also used to like Piers Anthony's books when I was young, and too naive to pick up on how much the author seemed to like writing about little girls panties and fetishizing pedophilia[1].
Some people can ignore the problematic elements, and some can't. You don't have to read The Shadow Over Innsmouth as metaphor for race mixing, but once you know it's there, you can't unknow it.
