Any President can change their mind about executive orders.
Every President can't change their mind about the limitations imposed on them by Congress.
This is a very simple point. I'm sure you get it. I understand, you're mad at Barack Obama. Fair enough. But getting Barack Obama to play nice doesn't fix the fact that current law regarding surveillance is bad and must change.

> count the number of presidents that have not changed it
> compare cost of serveilance today versus the EO date
Technology has changed the meaning (practical ramifications) of the EO.
POTUS can re-ballance the EO without congress.

Congressional obstruction-ism is no excuse for his 6 year inaction.
