While this is true, the reformists are a product of popular backlash against social restrictions like mandatory hijab. After the assassination of general Soleimani people voted for the principlist Raisi. Raisi brought back the morality police and harrassed teenage girls on the streets over hijab. This created a massive backlash that resulted in the hijacked protests and return of the reformists.
If the principlists roll back the relaxation of hijab and other social issues there will be backlash again and people will be divided. The principlists can only blame themselves for the election of Pezeshkian, Rouhani etc. The man in the video does not sound like he learned this lesson.
