Every time someone cries and moans about "betrayal" in terms of anime from CN, I get physically ill.
It's obvious that mainstream popularity of anime was a brief fad, and the only reason Cartoon Network was airing so much anime on Toonami and Adult Swim is because during this period of time, the ratings were above average. Many tweens and teenagers have since moved on, and only otaku remain. They aren't pulling in the ratings that are acceptable by the network, so they scaled back how much anime they air, and when they air it.
It's sad, but you can't be mad at them for being concerned about bottom line. The only thing you could do as a consumer is to spread word of mouth in an attempt to boost ratings.
Sci-Fi has typically lower standarRAB in terms of ratings, especially during the late night weeknight slots (as evident by their programming catalog being pretty pathetic), so to them, otaku nurabers are probably their average.
