The FR is effectively a canon part of D&D. One of the main MMs has Volo's name in the title. Orcs being optionally playable is an unarguable part of D&D, and not just in Eberron. Orcs have moral freedom by default, in D&D. That their 5E statblocks are all/largely CE merely reflects the default status of those particular types. This has been consistent across basically every edition possibly barring 1E.
Any specific campaign doesn't really affect other campaigns. Yes, we have a "voice" behind a book. We also have spells named after Rary and Leomund. So?

By whom? The cat's mother?
What an utterly meaningless claim, and without any kind of citation or evidence. That's basically weasel words.
You just stated:
Demons and devils are all evil (barring weird counter-magic) because the lore and text assert that they are all evil because they are essentially magical representatives of evil.
You
just claimed that all demons and devils are evil.
What the MM actually says about fiends is:
Fiends are creatures of wickedness that are native to the Lower Planes.
Says nothing about being magical representatives of evil.
Meanwhile, the MM "
lore and text" on orcs says:
Orcs are savage humanoids with stooped postures, piggish faces, and prominent teeth that resemble tusks. They gather in tribes that satisfy their bloodlust by slaying any humanoids that stand against them.
It then goes on to explain they were a race created by a vengeful god. From a purely rules text point of view I don't see a difference.
Yeah they're actually a hell of a lot closer to a human than a fiend is. That's not even arguable. They're mortal beings for starters, not immortal representatives of evil.
Which is a statement not supported by any text in the core books. Neither orcs nor fiends are human.
You may decide that some monsters are closer to human and it may be part and parcel of certain campaign settings. It is not a statement made in any of the core books that I know of so all statements of "X is more human than Y" about fictional creatures cannot be a fact and is instead an opinion and ruling. Feel free to rule differently than I do.
You are drawing a different line on when it is acceptable to say a non-human monster is evil than I draw.
