Piker is fucked for saying those things, but I can't agree with any kind of GamerGate style attack on anyone because of what they say. The implications of these advertiser-based attacks on freedom of speech are more than trivial.
I do understand the principle behind this take, I really do, and in theory at least I agree with it. However we now live in a world where acting on high-minded principles means that you lose, and when you lose, you get FUCKED. Consider this thought experiment:
Your country is being invaded by hyper-commie-Nazi-rapemonsters. They have started using chemical weapons against you, and as a consequence they are winning. Hard. If they win they will send you and everyone you have ever loved and cared about to the rape dimension, forever. They don't have any principles or any rules, other than a fanatical desire to win at all costs. If you draw a line in the sand they will cross it and spit in your face. Your side is losing so badly that you have 2 options:
1 - Gas them back
2 - Rape Dimension
The principled stand would be that chemical weapons are immoral, and that you don't want to descend to their level of barbarism. That's understandable and righteous. But it will also lead to the Rape Dimension. The Rape Dimension is worse than chemical weapons, especially as the only people currently NOT being attacked by chemical weapons are the ones using them without any second thoughts. The principled stance in this instance will lead to the worst possible outcome.
There is an old Roman legal maxim that goes: "Let Justice by served, yet the heavens fall." To which John Stuart Mill replied "If the heavens fall, justice has not been served".
The entire ecosystem of Twitch, and frankly globohomo-controlled media in general, is corrupt from top to bottom, and it is over-run by scumbags like Hasan who have no principles at all. Their only response to the restraint and mercy of their enemies is to see it as weakness and laugh at it. These people are fanatics who see no price as too great to pay for victory. To stand by high principle now is to let them win.
So burn it all down. Nuke it from orbit. Smother it with VX. Drop plague on it. It is beyond saving, and not worth saving, so destroy it by any and all means necessary, including the methods of the enemy. Maybe invent some of your own. The only way forward at this point is to try to build something better from the ruins of the old.
This does not necessarily apply just to Twitch. It also applies to Minecraft.
