1. If you buy that the people in this ad are Real People Not ActorsTM, well, I guess you're half right- they aren't "actors" in that they can't act. They are not, however, actual customers of some kind of mailing service who are in a Candid Camera/Punk'd situation and if you think they are, please show yourself out and don't come back.
2. I mean, the woman we see "was wanting to mail this..." and she has a letter in her hand. She looks like an adult to me. Which means she's heard of this thing called the United States Postal Service, which was founded less than a year after the signing of a piece of paper called the Declaration of F--ng Independence. Why is she going to some shipping company to have a letter mailed?
3. If this service is boasting of providing encrypted, totally private delivery of texts, well, what's the point in a country filled with people who carry on extremely sensitive conversations on buses, at the grocery store, sitting at Starbucks and basically everywhere else? The people who developed this thing think that they live in a country where people are concerned about privacy? Where did they get this idea?
4. Oh wait, Meta is behind this? The company that owns Facebook, everyone's favorite source of hate speech and election-altering misinformation which is currently losing billions in revenue and probably won't exist at all two years from now? That Meta? Yeah, pass. I mean, "not owned by Elon Musk" is a positive, but not THAT big of a positive. Meanwhile, I've watched this garbage several times now and I still can't quite figure out what they are trying to sell me here. Nor do I really care.
