Many people are able to understand the principle of if it's free then it is probably being financed by the use of adverts. TV, radio and the for the most part, the internet. BUT if people are paying for their products/devices then the need for ad's is just pure greed.
Apple are a trillion dollar company and they got there without the need to ad's. So why the need for ad's? are they making huge loses every year and need the money from advertisers to keep the company afloat? no. So why are they doing it? greed.
Which is why Samsung are doing what it is they are doing, just pure greed.
A couple of years ago I remember seeing DIY youtubers making 'Smart Mirrors'. They were building mirrors that had tiny computers built into them that displayed info on the mirror. How long will it be that every new build property will have 'smart mirrors' as standard in bathrooms and other rooms built into the property for the purpose of being able to show ad's to the home owner. We see ad's on the TV, we hear them on the radio, we see them in DVD's and Blu Ray disc's, we see them on our portable devices, mobile phones, watches, tablets. We see them on digital boards in shops, at train stations, at bus stations, at bus stops. Anywhere where there is a digital screen big enough to display an advert, the company making the product/device will make it so it can show adverts.
The more digital advanced society becomes, the more adverts society will be seeing and in more places as well.
