One person's "did well" is another person's "barely tolerable version of something deeply suspect." Directly telling people that certain races are inherently more "common" than others is a great way to stifle creativity, and forestall its growth in both new DMs and new players. Particularly when every "common" race (with the sole, and explainable, exception of human) has multiple well-known settings in which they don't exist, while several "uncommon" races (or close analogues thereof) appear in nearly as many places as so-called "common" ones do. (The Tales games often lack dwarves, and TES definitely does; Narnia and Guild Wars' Tyria have no elves; all four and WoW's Azeroth lack halflings.)
Totally agree with you. What's common, uncommon or non-exist should be listed on a per setting basis. So in Forgotten Realms, Tieflings might be uncommon while Elves are common, but in another place the opposite might be true. Or, hell. In a Forgotten Realms Underdark campaign, Drow, Dwarves and Svirfneblin might be the only "common" races and everything else might be "uncommon".
I also think that "I dislike them so I'll ban them" is a pretty stingy move from a DM, as well, especially if there's a player that would love playing one. Discouragement, I can understand. "If you play a dragonborn, people will be suspicious of you and they will more readily turn hostile", is fine, is all fine in my book.
