These contractors were hired to view this data. Your defense of Meta here doesn't make sense. Meta fired them for speaking out about the data Meta collects, not because they saw the data they were hired to look at.
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.)
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"

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