I won't comment on whether or not this is "the most important thing for our sport", I think that's a pretty personal thing with about a million correct answers. However, some of the comments on here seem to be a little misleading.
Bringing up "what happened with moguls and aerials" is actually quite off-topic. If you really want to compare Olympic halfpipe skiing to anything, compare it to snowboarding.
Yes, FIS runs the Olympic halfpipe snowboarding, and yes, it will someday run the Olympic halfpipe skiing. However, UNLIKE FREESTYLE AERIALS AND MOGULS halfpipe snowboarding is nowhere close to being domineered by FIS. The riders generally get to do what they want, when they want, and those that want to go to the Olympics get a chance to go. Yes, they have to jump through some hoops to qualify, but it's their choice.
it's certainly not as if someone like Danny Kass's career has been centered around or in any way controlled or hampered by FIS for the last 10 years, but during that time he did have a couple of opportunities to go win Olympic medals.
XGames, Dew Tours, WSI, etc are all events that run both ski and snowboard halfpipe. It's time the Olympics got with the times and became equal opportunity as well.
It's about additional opportunities and choices for our athletes, which equals more freedom to choose. The pro, and rider driven events will still be there (just like they are for the snowboarders), but if our top pipe athletes want a chance to compete at the Olympics (and they all do), then they should have that opportunity.
Consider this, what is more in the spirit of "keeping our sport free" - giving the athletes choices and opportunities, or denying them choices and opportunities?
