What did we learned nerds? The World doesnt hate Europeans enough 
I've noticed it too. I had practically avoided all online discussion pertaining to the World Cup until the final, so I was really taken aback by the amount of hate I saw. Not that they don't deserve it. I've even seen people say that Argentina is the Israel of Latin America. They're not wrong, but it's really surprising.
I don't know if it's artificial though, because from what I can tell, both Argentinian players and fans have essentially been behaving like Pissraelis throughout the entire tournament. That doesn't exactly make you popular. It's been an endless torrent of playing dirty and being unprofessional, hurling slurs, being violent, etc. I saw videos of racist abuse against Ishowspeed, and he's a very popular streamer. He even refused to accept an autographed t-shirt from Messi's wife.
To me it seemed like no one cared about the Falklands stuff except for British chuds who were seething when Argentinian players were holding up Malvinas signs to get a reaction out of them. That even pissed off Piss Morgan.
