its a secret experiment created by the League of Nations. As we are rapidly approaching the maximum number of humans the planet earth can sustain, 'Project Vanilla' was created, the final product? Cookie clicker. People who spend large amounts of time on the game are added to a list, and their individual prescription medicines, vitamin suppliments, and in some cases home's water supply is laced with a special compound, known by the code name of "8LIHEG89", codenamed "Sweet Brown Sugar", that will silently begin work against their reproductive systems, ultimately leading to complete sterilization. That way people whose traits are unlikely to benefit the human race(such as the particular combination of mental faculties that would make cookie clicker seem appealing) are removed from the gene pool, thus benefiting the human race's overall future by removing lazy, incompetent, easily amused, and rather dumb 'shut the brain down for hours on end and do nothing' traits from humanity's future. They do the same thing with reality shows, but the internet demographic doesn't cross over to the reality shows as much so they came up with another one.
