I wrote about this in another thread but I think WOTC sidestepped the real issue rather than having an adult conversation about how to avoid painting an entire sentient species as all bad. A page in the DMG about how to handle sentient races in campaigns could have done a lot to help the situation.
As it is, they removed orcs and drow (the two biggest offenders of racial stereotyping in fantasy) and a handful of others like duergar. But they leave in other species like lizardfolk, aarakokra, minotaurs and others who ended up becoming playable species in other books (and are if you actually consider Mordenkainen's Tome of Foes compatible).
The new description of the minotaur shows me how they could have handled it. Not every minotaur is a manifestation of Baphomet just like not every orc has to follow Gruumsh, not every duergar has to follow Asmodeus, and not every drow has to follow Lolth. Explaining that "you are what you do" is the conversation they should have had instead of coming up with some excuse to not include orcs and drow.
WOTC patted themselves on the back for turning gnolls into fiends but their own setting, Eberron, treats them differently, along with other species like goblins and hobgoblins. Changing "humanoid" to "fey" doesn't solve the problem. It bypasses the problem.
And, in bypassing the problem they break backward compatibility because many older books reference orcs, drow, and duergar and have expectations about the features of those stat blocks like poison for the drow and enlarge for the duergar that aren't served by using generic NPC stat blocks. Orcs have been one of the most common monsters in the game for 50 years!
So yeah, I think it was a mistake to not address the issue and instead waving their hands and pretending it goes away. The same is true with their changing of "race" to "species" and calling the job done. Both A5e and Tales of the Valiant recognize the value of splitting lineage and heritage (or heritage and culture). But WOTC does a cut and paste and says it's all solved.
