To successfully process a PERM a company needs to make the argument that they’ve tried and literally can’t find anyone else in the US to do the job. Thats obviously a very high bar, but for many years it was on open secret that companies mostly fudged these claims.

With so many tech layoffs now it would be nearly impossible for most roles to claim there’s nobody else available, and under the current administration the historical games are no longer just flying below the radar. That hasn’t stopped some companies from still trying though.
