In TOS, most of the Enterprise crew, and really the majority of the Starfleet characters we're shown, are exceedingly racist to Spock with disconcerting regularity. Of the regular cast, I think the only ones who aren't overtly nasty to Spock at least some of the time are probably Uhura and Sulu; they get frustrated with him at certain points, but generally because he's a difficult and inflexible supervisor rather than due to racial animus. A lot of the rest of the crew is openly hostile, and McCoy routinely addresses him with slurs in front of the bridge crew. Kirk tolerates and sometimes participates in this racist abuse, and the only times he seems to take it very seriously are when it threatens to become an operational problem (as in "Balance of Terror"). The main feature that comes to characterize the bond that develops between Kirk and Spock is not that Kirk is significantly more tolerant, but that he will usually (not always) at least listen to Spock's point of view, which the rest of the crew is very reluctant to do (most pointedly in "The Galileo Seven"), and can be persuaded to respect his judgment, which Spock values even though Kirk's attitude and behavior still often make him uncomfortable.

This kind of space-racism toward nonhuman Federation citizens is not necessarily a structural element of STAR TREK (unlike anti-indigenous racism, which definitely is), but it is a structural element of Spock's character. Spock spends a lot of TOS teetering on the brink of a nervous breakdown, and it's tempting (though not canonical) to read his decision to pursue Kolinhar in the beginning of STAR TREK: THE MOTION PICTURE as a response to the stress of being on the Enterprise (fleeing to become a monk!). Even where Spock is not enduring racial slurs and constant microaggressions, you can see how that treatment, both in his youth on Vulcan and as an adult in Starfleet, has shaped his personality. Indeed, this is something I think to which fans of Spock have responded strongly over the years, because his alienation and stress are very relatable for LGBT people, people of color, Muslim and Jewish people (despite STAR TREK's canonical antisemitism and Islamophobia), and autistic people. This doesn't mean STAR TREK stories necessarily have to show Spock being tormented, which is often painful to watch, but if Spock had not been tormented in these ways, he would be a very different person than the character viewers know and love.

Making Spock a regular in DISCOVERY and later STRANGE NEW WORLDS thus presents the writers with a problem: Treating Spock the way he's treated in TOS would be uncomfortable, but avoiding it creates a tension with TOS that the newer shows obviously don't know how to resolve.

Prior to ENTERPRISE, the general presumption about the TOS era (which is stated as fact in some of the novels) was that having mixed-species crews is relatively new for Starfleet, and that the problems Spock faces stem from his colleagues never having lived and worked with an "alien" before and not knowing how to not be weird about it. (ENTERPRISE essentially transferred that idea to Archer's era, where T'Pol gets similar treatment.) In DISCO and SNW, however, we see that many Starfleet vessels have mixed crews, including officers (like Saru) who are much more obviously nonhuman than Spock is, and have for a while. So, how are we to read the events of TOS, with which DISCO and SNW still want to (uneasily) coexist? Is Kirk's Enterprise just a lot more racist than Pike's? That's possible, I guess, but how many STAR TREK fans really want to canonize the idea that Kirk and his crew are unusually intolerant by Starfleet standards? Are we to presume that SNW means to soft-retcon the hostility and constant microaggressions Spock experiences in TOS, shifting the entire onus for his twitchy alienation to his upbringing on Vulcan and to Sarek (who DISCO reiterates is a tremendous dick)? That would be sadly consistent with the disdain with which modern STAR TREK media treats Vulcan (and with the antisemitism of the modern shows), but it's a pretty bitter pill for anyone who thinks Vulcans are neat or cool, which used to be an uncontroversial majority opinion among STAR TREK viewers and writers.

The more sensible answer would have been to just dodge the issue entirely by staying further away from TOS and the period in which it takes place. There are other periods of the TREK timeline that are still largely unexplored (like the early 24th century era of the Enterprise-C), and there's always the option of moving further forward in time, as DISCOVERY eventually did. However, CBS seems very insistent on making heavy-handed appeals to nostalgia that require riding the coattails of TOS, even where that just doesn't seem like a good idea creatively.
