How bad REALLY was audience reaction at 2nd day of this festival?

I have an impression that this topic was blown over the internet, basing on one or two unhappy reddit post and some comments that follow. But how did it ACTUALLY look like there? Question to people who attended; was there really so much "booing" that musicians could've heard "unpleasant" audience and decided to not play the last track? (I've seen some article stating this and honestly it just doesn't fit in my mind that could really be true)

Honestly IMO if you're going to SUE the band for not meeting your expectations, you'll just confirm to be the worst stereotypical snobbish fan, and if it really happens we could probably say good-bye to any new music of theirs (if you remember the trial drama after 10,000 days)
