There are many alternatives to modern marketing, which is specifically made to manipulate you, through emotional, aspirational and fear-based psychology.
Word of mouth is probably the most powerful one. If someone you trust recommends you a specific app, that's better than any marketing campaign. Why do you think astroturfing exists?
If marketing was solely based on showing a product in an honest way and listing its properties and specifications, with no hyperbole and exaggeration, that would be something else. When was the last time that sort of advertising was the norm?
Advertising used to have lots of text extolling the features and benefits of the product in question, but that's too complicated. Now it's just bright flashy colors and vague allusions to power and capability. BMW has been running an ad on Youtube for a while now about a new electric model, and the voice-over basically says "there are so many reasons why car is great, it would be impossible to list them, just trust us and buy it", they're not even pretending to tell you about the product itself.
Marketing doesn't incentivize innovation, it tries to sell you an inferior product at a higher price.
