Picking a successful stock at past point you didn't buy in at is a hell of a sampling bias. The peak of /r/wallstreetbets activity was people throwing in money at the $250-$300 level trying to will it to $420, and it's now below $100. If you were smart and bought before the peak hype... how many other equally promising-looking stocks did you also buy into, before a hype that never arrived? This article definitely isn't bias-free either but at least it's not picking stocks based on performance.
