I mean, this Playtest shows an Orc that is obviously designed to change that approach, doesn't it? In fact, Orcs have been portrayed positively in TTRPGs and videogames since, like, about 2000, pretty reliably. Hell Shadowrun has a positive portrayal in 1989. WotC was been a stick-in-the-mud about it, and with 5E, actively tried to drag Orcs back to being analogous to racist stereotypes with Volo's. Then WotC realized they screwed up big, and are now trying to fix it. It's kind of late in the day, given Shadowrun understood this the "racist" take on Orcs was dumb 33 years ago (and that continued in the "Let's Fix D&D" RPG that was Earthdawn in 1993, which presented Orcs as just another race), and WotC's own Eberron showed it was dumb even in a kitchen-sink D&D setting 18 years ago. But I guess Mike Mearls (who took personal charge of Volo's) wanted to drag things back to an older place.
That's just nonsense though, as your own "fun-loving goofs" comment indicates. 80% of Tieflings, like, since 2E, have been played as characters who not particularly "edgy", let alone "angsty" - and indeed, you seem to unaware of what
@Kobold Avenger mentioned, and which has long been true, which is that they've been the unofficial "LGBTQ" race - i.e. people who are LGBTQ have often chosen to play them. So sneering at them as "edgy losers" shows you're kind of misunderstanding
why people play them pretty profoundly.
I've never actually seen a Tiefling played as particularly non-ironically edgy, when I think about it, despite having seen them regularly since 2E. In fact edgelords in D&D don't seem to pick the theoretically edgy races except maybe Shadar-Kai in 3E. Most Tieflings, Drow, Duergar and the like I've seen have been "against-type" characters (and not Drizzt-like "edgy loners", either). The only consistent thing I've seen from edgelords in D&D, in fact, is picking races with strong combat capabilities (particularly STR bonuses when that was a thing). I've seen human Fighters who were gigantic edgelords - hell that might even be the most common race/class combo for edgelords playing D&D (obviously that's a very small percentage of people playing human fighters overall, to be clear).
