It is unethical from a photojournalistic standpoint, where failing to check whether "Michelle" is spelled with one L or two for the cutline is also considered unethical — but I don't think most people would consider it deceitful.

The message is all truthful, so it is still a step above the propaganda discussed in the OP.
