Meta's Layoff Approach - Is it Legal or Ethical?

Honestly, reading about these recent layoffs at Meta, especially the claims about how decisions were made, really got under my skin. It's being reported that the company might have used algorithms to identify employees for termination, and worse, that it targeted people who were on medical leave or parental leave. This is beyond just a tough business decision; it feels like a massive violation of trust and potentially illegal. How can a company that built its empire on connecting people now be accused of such impersonal and possibly discriminatory practices? I understand restructuring is necessary, but using automated systems to decide who goes, especially if those systems are looking at sensitive personal data like medical history or family status, seems like a huge ethical red line. I'm curious if anyone else here has direct experience or knowledge about how these decisions were actually made. Was there any human oversight at all? This whole situation is deeply concerning and I hope there are serious consequences if these allegations are true.
