layoffs.fyi says "72 tech companies w/ layoffs" right at the top, big and bold - it's pretty clear it's only tracking tech companies.
More to the point, tracking "tech layoffs within non-tech companies" is impossible with public data because that information is rarely broken out.
Things are worse than many think.
Which begs the question, what is a tech company anymore or a non-tech company?
Aside from the fact that they use technology (but everyone uses technology), ebay is not a tech company. They don't sell technology product.
