I don't know, I don't 100% agree with your assessment. Their marketing isn't really "honest" but more "simplistic".

Disclose less and you can fault/blame them less.

They don't disclose much and barely ever compare truthfully.

In terms of disclosure for instance they'll say 10% more battery life, 10% more than what and under what conditions?

Humans are bad at mental comparison, they'll forget we shouldn't be comparing to the 2 year old device that's a fallacy.

I think for the most part it's copium. People don't like to be wrong or conned. Apple disclose little enough information that the consumer can't feel they were duped (e.g. "they didn't say it's 24hr battery life, this must be normal") and little enough that they can justify any shortcoming as inevitable for the technology (e.g. "I can't install an app, hmmm it must be safety or something").
