Meta didn't fire individual independent contractors, they terminated a contract with a vendor. It's possible they did so because some of the vendor's employees spoke out but we don't know the real reason.

(I do think these smart glasses are super creepy and I'm not defending Meta's data collection practices.)

This is some real weird defense going on here.

> but we don't know the real reason.

We know the course of events. We have brains and can reason. You really expect Meta to come out and say "Yep, we fired them because they whistleblowed"

> I'm not defending Meta's data collection practices

No but you certainly seem to be over here quibbling about epistemology in the defense of Meta
