This point in the article was weird to me, that you should creatively avoid saying that you were laid off. Sure, some layoffs are just an excuse to get rid of people who the company believe are low performers, so if you were laid off from a prominent company where recruiters know why the layoff happened, this could be a problem for you when looking for a new job.
But if you were caught in the string of layoffs happening this year (or at the beginning of the pandemic), I can't see how there'd be stigma attached to that. And I'd worry that being evasive about why you're no longer at your previous company could be a red flag to recruiters; just doesn't seem worth it.
