In Indonesia, the World Cup got around 74% of audience share.
The company who got the rights here are bastards who thinks people don't watch terrestrial TV anymore and their agenda is to force everyone to watch from their shitty streaming site. During the last match day of group stage, only one match is shown on TV despite the group owns multiple TV channels in this country.
They even monitored and enforced the rule for big cafes, bars, or any other places that had a public viewing to show the broadcast from their site.
As I had said above, their site is shit and looks like the bandwidth was unable to handle the number of viewers during the final. So people were angry and posting their own experience watching from the site (sudden timeout, stuttering images, sudden logout from the app, crashing app, etc)
If you read my post during the finals, you can see I was having issues too
