The video is being shared by the PKK using the KRG anthem in the videos they publish despite it being a different dialect.
This is clearly to enhance recruitment in Iraq, increase support for Bafel Talabani of PUK who is said to be taking a stand against Turkiye and reduce Barzani's power, especially with elections coming. It will be exceptionally dangerous if PUK win majority in KRG like they did in Kirkuk as this would mean Iran dominating the north as well.
Problematic as Barzani is who the TSK cooperate with to limit PKK movement. Instead we are humiliating Barzani, like when we blurred their flag as it's election season
Barzani speeches calling the PKK terrorists was very important for TSK, as part of the whole PKK doesn't represent Kurds. But as an asset we have weakened his (ours) hand
The first tweet above shows the type of support PUK is getting and how this anthem connects PUK, PKK to a wider audience
