Why? Because there are/were more warmongering republicans than there were Ross/Assange fans. Not even close. So it is either Ross and Assange or keep and grow power.
And if Assange wanted, he could have just followed Snowden to Russia. Also Trump, Tate brothers, and even JStark and even Jesus Christ could have just lived their great lifes instead of going through all the trouble.
They fight their fights their way. Since for whatever good or not reasons we continue our comfortable lifes while not much contributing to those fights, we are not in a position to have strong opinions on how which of them should sacrifice themselves or one another.
