Lawsuits citing algorithmic decisions for layoffs - what's the real story?

Been seeing a lot of chatter and a few lawsuits popping up about Meta supposedly using algorithms, maybe even looking at things like medical leave or parental leave, to decide who gets laid off in the recent cuts. It's pretty wild to think that a system might be making these huge career-altering decisions instead of actual human managers. The lawsuits claim the process was discriminatory. I can't even imagine what that would look like internally. Were performance metrics the only thing used, or did they dig into other data? It makes me wonder how much of our data is being used in ways we don't even realize. Has anyone here heard any whispers internally about how these layoff decisions were *actually* made? Beyond the official HR statements, of course. Just trying to get a sense of whether there's any truth to these claims.
