Treason in the context of the United States is the act of a citizen betraying his/her fellow citizens by aiding our enemies against us. Neither Assange nor any other non citizen can commit the act of treason against the United States.
Assange is being accused of conspiring to break into a government computer not treason.
The fact that extradition isn't an equal thing isn't exactly shocking its a function of treaties between the relevant nations and wherein a power imbalance exists between those nations the terms are less likely to be equal and the US is still one of the most powerful nations on Earth.
Ivo is getting extradited for attempted extortion which he committed in the Czech Republic and when people commit crimes from the US against international parties they can also be charged with the a crime for those acts supposing they are against the law here.
Punishing acts where victim and criminal are members of different nations is often complicated. Few nations are eager to subject their citizens to foreign laws.
