I don’t think Messi by himself does, but Milei used football (and his team) to promote politics. Not only did he tie his team to his stupid politics in Argentina, but he invited Israel to do so too. Many israeli ministers got to meet up and get photoshoots with the team. Even Netanyahu said he wanted Argentina to win.

Such a sport event was inherently politic, just like Eurovision is despite their best efforts to say it isn’t. But purposefully using it to promote your politics by blatantly associating your country’s team to both your ancap government and Israel’s government is kind of a dick move, and no other country did.
