The problem is that the article does not describe a repeatable process. Maybe the author's experience is repeatable, but that is not part of the content. The most critical component was the marketing, i.e. "going viral" on Twitter. Some marketing firms specialize in doing so and seem to have skill, yet I see no indication of where the author intentionally took steps to achieve that effect. Therefore, yes, it does seem like the author "got lucky".
It may not be a perfectly repeatable recipe (that doesn't exist), but there's solid, actionable advice here. Particularly "act immediately". Things only go viral when the moment is right, and that moment is usually very fleeing.
One supporting data point: back when the game 2048 went viral I happened to be on a break with nothing to do, so I coded up an AI for it in one night [1]. The next day it blew up on Twitter and elsewhere. There have since been many other, better AIs, but since mine was first and came out when the game was on everyone's mind, it was the only one that got so much attention.
Since when is “repeatable process” a requirement for not being qualified as “lucky”? Maybe the OP is just a talented and dedicated person who delivers high quality work, and because of their dedication, was at a place where they were ready-to-go and seize the opportunity when iOS 14 arrived.
Someone much wiser than me once said, “dedicated people can force luck to happen”, implying that it’s only a small part of the equation.
Is that a problem, though? A major component of success is in fact luck. Doing the right thing at just the right time, with enough prior planning and skill to be able to follow through if it takes off. If making a bunch of money somehow with few hurdles was reliably repeatable, everyone would start doing it. Until the market is saturated and then it stops being repeatable.
First mover advantage ties into this here, as does discussions on the free market, and other interesting economic theory.
I have to disagree that a major component of success in business is luck, generally speaking. A successful business relies on having repeatable processes that generate profit. If one wants to talk about becoming a billionaire or growing a social media company to the level of IPO, then I concede that an above-average degree of luck is involved.
