The Anonymous they uploaded one video addressed to the Greek people on the occasion of the upcoming referendum, which in the end we do not know if it will take place. 
"We do not support any political party, but we must congratulate Alexis Tsipras for his stance and his decision to hold a referendum," the hacktivists said.
Let's say that channel of the Anons Greece uploaded video is highly politicized and you will find several things you can see.
Watch the Anonymous video that urges all Greek citizens to vote "No".
The video is in English with Greek subtitles, translated by Anons Greece.
