Marek Prihoda, one of the main organizers of the summer school where Rubtsov lectured, expressed disappointment, saying, "We are very sorry that an agent of a foreign country deceived the organizers and participants of the summer school." Rubtsov had been involved in selecting students for the program and also reported on members of the opposition Ilya Yashin and Vladimir Kara-Murza, who up until recently were also imprisoned.
