Article title isn't super clear, but this is for video game developers who have either been laid off themselves OR others on their team have been impacted. It's still bad, but the 35% quoted as impacted in the article is not actually a percentage of layoffs.
According to the report, while 54 percent of developers canvassed said there had been no layoffs at their company over the last year, 35 percent said either they or their colleagues had lost their jobs.
Yeah, its 35% of the people canvassed for this report. Even then, not all those people were laid off - some of them are people who know somebody who was impacted.
