If anyone has a better source for this info lmk, I know that some guy on r/gunners had a nice graphic but I have no idea where to find it...
My thinking, and it’s just a guess here, is that it’s a measure to reduce traffic to the site so the stream stays up and the servers don’t get overloaded.
That cost stops someone who’s casually interested in watching the match from tuning in and leaves only the “true arsenal fans” watching.
Just a guess but it’s the best guess I’ve got.
