Didn't Harshirama break free from Orochimaru's control using the same method as Madara? If so that kills Thekillman's theory that they have to wait until the technique is undone before they can release themselves. I go with actionmanrandells theory on this one. Madara probably had no desire to break the seal. He looked like he actually was having fun messing up the Kage. Honestly Harshirama and Tobirama couldn't have broken free from Orochimaru from the chunin arc because they were kind of emotionless and weren't as powerful. Remember later on when Orochimaru once again summons them, Tobirama tried to break free but isn't strong enough while Harshirama who this time was summoned at full strength broke free. I assume it takes a lot of power and enough free will to break the control like both Harsh and Mada.
