Eh, doorbell cams aren’t that controversial (ad aside). A lot of people have them already, both from ring (with the concomitant privacy issues) or from other providers (with different but similar issues).

They’re controversial on hacker news but I don’t think people in the “real world” care all that much.

How that connects to the meta glasses is certainly up for debate —- the doorbells provide a lot of value to the user (know who is at the door remotely!), the glasses are more of a mixed bag.
