Difficult to say. If you keep in mind, that he wrote the sequels 30 years or so later and acknowledge that one’s views change over such a period, then go ahead. If you, however, expect the same flavor as the trilogy, then I wouldn’t recommend reading foundation’s edge and foundation and earth. And although these are meant as an introduction to the men behind time, that one makes no reference to the foundation trilogy. So it’s fine to just read the end of eternity on its own.
I just checked it out, because of your claim, but found it to look just like it always did. r/all is still the same, my subsribed subs are still the same. Still a lot of people posting content, asking questions, sharing stories. Not sure in what kind of bubble you live :/
