I don't disagree with that sentiment at all. These company's min/max their strategy and operations regardless of the human impact and that is terible. However, I find the sentiment irrelevant to calling out a fallacy in the thinking through the article that layoffs are social contagions.
I wouldn't say all the tech layoffs are a social contagion. But amongst tech companies with extremely healthy balance sheets and income numbers, definitely more social than economic phenomenon.
