Reddit doesn’t have half the world population, that would be 4 billion people.
Reddit has 73,100,000 daily users worldwide and 267,500,000 weekly users worldwide. Not 4 billion.
And also, this is biased towards Reddit because the first questions asks if KT and Reddit have subreddits. Those are exclusive to Reddit and they’re just clubs. Instead, you should compare how KT and Reddit have clubs and compare the privileges and stuff like that.
