Because some idiot playing Minecraft on YouTube is more of a profitable brainchild to those who don't give a fuck about politics, and the fact you can find obscure live comedy skits on even Twitch is more financially stable in the long run.
This anti-Trump brigade has not only gotten so old, but the only reason I am still laughing at it is because of the persistence in lowering the rung of what is intelligible hysteria. There are people who dislike Trump for understandable reasons, others just hate him because that guy with the unkempt hair on SNL told them to. Individualism isn't a thing and had stopped being a thing around the turn of the 21st-century. That's all Cable Comedy has to cash in on now, and when Trump's turn is eventually over they'll have absolutely nothing to work with.
