I know a site like this can never be accurate, but the non-tech company I work for had a significant reduction in tech workers and isn't on the list. I really think that sound count.
For folks who are not in tech, check out WARNtracker.com which tracks US layoffs from all companies through mandatory government reporting from the WARN act of 1988, which requires layoffs above a certain size to be reported to state governments.
A good complement for Layoffs.fyi (Sometimes the source of a layoffs.fyi entry will be an article written by a journalist who saw the WARN notice on WARNTracker)
It's not as bad as last year, but if you look at the layoff.fyi graph that goes back further (https://layoffs.fyi/#tabs_desc_471_2 ), I remember feeling that around September of last year that the huge amount of layoffs from late 22/early 23 had stabilized: a lot of my dev colleagues on LinkedIn that were previously laid off had found new jobs (but non-IC-eng roles definitely didn't fare as well), and there were even reports of companies that had had big layoffs rehiring.
So I'd say I was surprised by the big layoff numbers from the likes of big names like Google, Discord, Twitch, Instagram, etc. this January. To me it had seemed like we had already hit bottom WRT layoffs but apparently not.
