I think you're catching it. You don't like my example, so I'll have to come up with a better one. I picked that one because it's an example of what some, but not all, people would regard to be playful hyperbole, puffery. We see it in ads all the time. We think it's cute, interesting.
First of all, it's not misleading. It doesn't mislead us. That's fundamentally the issue.
To the extent you think “save the planet” might mislead someone, I agree with you. If it is a matter of fact that it would mislead people, then I agree with you. Often these things are context dependent.
In the example, in fact, that I brought up the other day, if it were to say “save the Ottawa River”, or “save our waters” or “save our lake”, something that people might think is relevant and they're going to buy that product, then I think you're into a question of, well, will this really save the lakes? When you say “save the planet” or something that is equally distant from reality in connection with the product, which is all I'm saying, it would be, strictly speaking, false. Nobody would believe it was meant to be anything but false, yet technically it would be still be caught under this legislation.
If someone comes up with a better example, I'm happy, but that is the one that came to mind today.
