Most rational people 10 years old or above know enough to know that you should research a product before you buy it. What is the commercial/ad actually claiming? What does the fine print say? warranty? If a person is buying a product based on advertisement claims alone, that person has an issue, not the advertiser.
To be honest, I like that these companies are spending so much time trying to identify products that I might be interested in, but haven't had the time to research enough about it to make an educated choice. Google turns my searches into ads embedded into email, or searches themselves. I ask Alexa about something or the Alexa wikiHow app, and the next time I'm shopping on Amazon, I have targeted ads for those same items I had begun research on.
It's a beautiful time saver in my opinion. Once you've narrowed your search down to a specific item, you can read reviews, compare it to similar items, do a search on that same item.
That's the same tactic with selling data; the company purchasing the data is trying to connect consumers with product. If the consumer doesn't do their research and buys a shitty product, there are still several layers of consumer protection where the customer can be reimbursed.
As far as predatory gaming ads and games geared towards kids... don't give your kid access to your credit card, buy them a gift card. It's not that difficult. There are too many stupid people on this planet because technology has broken survival of the fittest; allowing stupid people to live long enough to breed more stupid people.
