300 academics from around the world have signed a petition where they express their support for SYRIZA and request that Greek people are allowed to vote freely without any outside pressure or influences.
Logically, if they want no outside influences, they must be conceding that they themselves are totally uninfluential. In which case, why bother writing a letter?
I read the letter as being more about what happens after the election, with the "right of the Greek people to make their decisions freely" referring to letting SYRIZA achieve the restructuring it wants. It says "At the same time, if Syriza is voted into power, its government will need massive support from the people of Europe in the face of the pressures from the financial markets and political forces which fear any departure from the obsolete framework of capitalist globalisation."
