In response with that video, I think Cartoon Network has been trying to send a message for a very long time, and I think this message is to tell everybody who grew up with Cartoon Network from the late 1990s-2012 is they want those viewers to grow up and to stop watching Cartoon Network all together.
Cartoon Network has been responding negatively towards older audiences, and the more we demand for change, they more they'll ignore us because now the network is doing this on purpose to piss off the older viewers even more. And now that they've abandoned all the older shows entirely, or rebooted our childhoods just to throw us off even more.
This is something I think the network is doing intentionally on its own, telling viewers of that era to stop watching their shows and pull the whole "cartoons is for kids, so grow up." This problem I can see rising for a very long time until new people are in charge of the network, which even then things could get worse?
Not only that, there's a strong lack of variety, now everything has the same animation, the same slice of life episodic shows. All they have to throw in is different voices and looks and it technically still is the same show. CN right now is only caring about releasing cartoons and only money endorsing Teen Titans Go, because not only do kids like it, but because we hate it with a passion so much they won't stop airing this show until we decide to stop watching Cartoon Network entirely.
I say that if this is the networks true intention, nobody is going to realize it until its over. And this might also be a thing happening to other networks right now, not only are they releasing bad content, but they're trying to push us out for the next generation, which has a totally different interest in series compared to us entirely.
So for now all we can really do is wait for this generation to end which won't be til around 2020 or even after that, or even when Christina Miller and the guy running the schedule gets F-I-R-E-D or steps down, and wait for the people of our generation to truly be hired to make better quality content in order to truly enjoy cartoons again.
