Nguyen famously removed the game from app stores shortly after it surged to popularity, stating that he felt guilty that people were becoming addicted to the game. This makes the game's reappearance — complete with loot boxes and other addictive features — feel somewhat dark.
On September 15, Nguyen returned from a seven-year Twitter hiatus to post: "No, I have no related with their game. I did not sell anything. I also don't support crypto."
Although Nguyen held the Flappy Bird trademark, he did not sell it to this group. Instead, they registered the trademark themselves after arguing he had abandoned it.
