I did read that back when it was posted. I hope you recognize PR when you see it?
Sorry if it came across like I was saying that companies are being evil or bad or vain about how they're hiring. Quite the opposite, and more dangerously, I think companies see nothing wrong with the boom-then-bust approach to hiring, and that it's going to happen more.
And so my point here is that employees need to re-think how they look at job security in high-growth companies, and assume that they might be getting hired as part of a "bet" and not as part of a long-term strategy where the company has allocated the money to keep you around, like a lot of people assume when they take a full-time job (vs. a contract).
Plenty of larger tech companies that did layoffs, Shopify included, were never in any real financial trouble. They just made bets that didn't pay off, and so they corrected and moved on.
