Advertising and marketing is not market manipulation, it is a strategy to attract more potential consumers thereby expanding the reach of the target market. Maybe in practice there are several marketing techniques to manipulate people's minds to encourage them to buy the product. But still it doesn't have a direct influence on statistics, it's just a possibility.
I agree that advertisement isn't a kind of market manipulation. There is nothing wrong with advertisement, it is a common way to invite more people joining/using a product/service. If people think an advertisement is convincing enough, they will follow it. While if the advertisement seems not interesting, people probably ignore it. So, it doesn't automatically increases the number of customers/demands, it depends on how effective and how the quality of the content of an advertisement.
It is different with market manipulation, it is the action that make an automatically raise/drop of the demand. For example when the whales manipulated the market, the price of a coin can free fall because whales are spreading FUDs through social media. Or the whales are trying to dump the price of a certain coin by selling a big number of the coin.
So, the way of an advertising (advertisement) and market manipulation are quite different.
