I was in a bar that did not pay for it during the time of the fight. Multiple people were streaming it on their phones, some via the bar's wifi and some via cellular.
What was hilarious is that every phone was in a different place in the fight, I was standing behind one guy who had it on his phone at the bar and the two bartenders had it on one of their phones behind the bar. They were out of sync by over a round at various points - the guy I was standing behind kept messing with it trying to catch up which sometimes worked so he was both behind and ahead by a parts of to an entire round at various points. The bartenders just left theirs alone.
After the fight was "over" I was walking to the restroom and there were a couple guys I know who were still watching the last round. What an epic screwup!
People I know at home were running into the stalling and buffering on their smart TVs so they were trying playstations, xboxes, PCs and phones and had more than one going. Netflix might claim 60 million streams but a lot of them were the same person trying multiple devices lol
