No, I have a problem with marketing that is intentionally deceptive and can easily confuse non-technical users into believing they're paying for something they're not.

Neither of your car manufacturer examples demonstrate this. However, when a certain US cellular carrier slapped a "4G" sticker on 3G technology simply to make their product appear competitive in the market that was not OK.

Similarly, implying to users the pixel density of their device matches the resolving capabilities of the retina, when actual scientific studies demonstrate otherwise, is not OK with me.
