Advertising is something a lot of people don't like, and the way it manipulates people can be underhanded if it's not regulated well, but it's not deliberately misleading or fooling anyone.
Not always, true; but there are plenty of cases where it does.
But you definitely cannot say that in general, contrary to other cases.
Why is it we "definitely cannot" say that in general? That's not obvious to me at first glance.
I know of many examples of ethical advertising and/or advertising that does actual good. For example nonprofits use advertising to raise awareness and funds. Without large scale advertising industry, it'd be impossible to reach that many relevant (interested) people. I used advertising to form a local social help group, that'd be impossible without Facebook.
What about fake 5-star reviews on Amazon? Don't tell me they aren't funded out of marketing budgets...
