Tuulik even had a message for his former colleagues (“comrades”) at ZA/UM, including Kurvitz and Rostov:
“To all other former respected comrades (Kurvitz, Rostov, everyone) – long time no hear, but we would love for you to join the struggle as well: time to roll up our sleeves and start building communism!”
Well yeah, but it's more about the principle of it, he's supposed to be a ZA/UM old guard and that was part of his value in being in the documentary, so it's not as if being fired should be a radicalizing moment.
Basically I think he appears a bit too flexible, the radical rhetoric comes off leaning more towards branding than deep principle.
