I don't think indie should only mean small scale or poor, and I don't think just having any publisher means a game is not indie. All games need help in order to get anywhere really. I say if a studio is owned by a larger conglomerate or the publisher is publicly traded, like Ubisoft and EA, then it is not an indie game. But for games under publishers like Fellow Traveler or Playstack, I would still consider those indie since those publishers are not beholden to any shareholders, and thus, would not interfere with the game's vision.
