Why stop here? We can also blame the people, who implemented such features on the TVs, the people who worked at companies, who used data acquired by these devices for advertisement, the people who worked on the mentioned ads for such devices and the people who bought products from companies, that spend money on such marketing techniques.

The average guy is exactly the person responsible for global warming. The evil of the world is just the meta accumulation of the average person following their mirco incentives.
