Hacker News discusses new sweeping rule changes in curling, including a ban on firmer broom foams, ahead of the Olympics. The changes sparked conversation about "Broomgate," a previous scandal involving technology doping in curling, and how the changes might impact the game's balance between finesse and power, particularly in light of the recent rule change of no take outs before the 5th rock. Commenters offered varied perspectives, ranging from disappointment at the potential loss of finesse to amusement at the sport's quirky nature. Some mentioned the evolution of curling techniques over time and the potential for equipment-related controversies similar to those in golf. There was also a humorous interlude regarding missed opportunities for "sweeping rule change" puns.
