Many of the messages linked the result to the conduct of several national team players during the pro-government night-time gatherings that followed the US-Israeli attack and killing of Ali Khamenei, singling out defender Ramin Rezaeian more frequently than any other player.
Rezaeian was slammed for his pro-regime stance in face of the massacre of over 36000 protesters during January protests.
"You were eliminated a long time ago, the moment you turned your backs on those who lost their lives," one viewer wrote to Rezaeian.
Many said the team's relationship with the public had broken down weeks earlier when some players attended pro-government gatherings and voiced support for the Islamic Republic after the crackdown on protesters. They argued that the loss of public backing ultimately affected the team's fortunes on the pitch.
Others described the defeat as karma or the result of the grief of families seeking justice for relatives killed during the protests. Several wrote that the team no longer enjoyed the goodwill and support that had accompanied previous World Cup campaigns.
Some messages contrasted the current squad with former national team goalkeeper Mohammad Rashid Mazaheri, whom they described as having stood with anti-government protesters. Mazaheri was detained after publicly supporting protesters and has since disappeared from public view, according to people familiar with his case.
Public support
Several citizens said the national team no longer represented the wider public, pointing to the absence of the large public gatherings and celebrations that had accompanied previous tournaments.
"This is not a national team that represents the people. We are happier to see it lose," one person wrote.
Others referred to a disallowed goal by Shoja Khalilzadeh, linking it to his previous remarks about dedicating goals to Iran's Supreme Leader. Some also pointed to Rezaeian's tears after the elimination, arguing the outcome reflected the political choices made by some members of the squad.
A common thread across the messages was the view that sporting success and public trust cannot be separated, and that distancing themselves from large sections of Iranian society ultimately carried consequences beyond football.
