You say suspicion is warranted, you're still not only charging forward with this but also complaining about other people's perception of you doing so. You're not being left out, you're included in the narrative. You just don't like it.
I hope, for the kids' sake, in addition to normalizing the idea that it's okay for dad to be recording them without their awareness, you teach them that most people find the idea of strangers doing this to be creepy and distasteful (for good reason), so they need to be wary around Meta glasses despite seeing them as a quotidian thing.
If you gave me a non-Meta glass like this, I'd happily switch, and FWIW, if I saw some evidence of Meta doing something untoward with this data, I'd dump them immediately. An unaction'd patent and breathless headlines over "creep glasses" is all I have to go on for now.

They're 2 man. You're at the point of questioning whether parents should be allowed to film their infants. Do we think we're off the deep end a bit?
