You are completely exaggerating and pointing out edge cases. Sure sometimes advertising can be harmful and there are laws against false advertising. But in general it is helpful and provides value. For instance I personally like it when I 'm shown a relevant advertisement which actually convinces me to purchase it. Just recently I saw some advertisement on Instagram related to some concert near where I live. It was actually relevant and I considered purchasing a ticket.
You can always exaggerate and cherry pick bad instances from anything. What you are doing is similar to this. There were a few Samsung phones that blew up and caused injury. You now characterise all phones as being harmful and dangerous to society.
Not an edge case at all - phones blowing up is not what we're talking about. The absence of "we spent less than 10% of our budget on cyber security (in fact, we proud ourselves in having less than 5 cyber security experts on the team, and our release cycle is very quick - we don't really listen to the nerds when they say they need more time!), so unless you'd rather avoid a 15 year old kid from Russia completely owning all of your personal data, our product is the most cost effective option! Also, we used existing circuit boards, so our phone's innovation is mostly on the cost side - we managed to make it dirty cheap for you. What are you waiting for?" is what we're talking about.
