Even ignoring implication of attaching traits to 'evil', traits that have been used to stereotype minorities in real life, making whole races evil 'because gods said so' (whether that's setting or writing gods) is just lazy writing to have faceless mooks to slaughter. Your group is itching for some combat? Just throw some orcs their way. At least now you don't have to write whole essays justifying yourself to your DM if you want to play one of those races as non-evil alignment.
And you can still play those races that way at your table if you want to. Sure, the opposite could've been done as well in the opposite case, but it's nice to see the people being paid for it actually doing the more labour intensive version.
