As a snowboarder whose never skied I couldn't make a direct comparison but I think it's more a case of competency rather than the sport itself being less in control. If I want to head to a certain point of the slope or avoid people around me I can do that happily and if I need to stop for any reason, making a decision where to go at a split/an issue down the slope/end of the piste/immediate issue in front of me, I can resonably do that too without taking anybody out. You do definitely see snowboarders wiping out and taking others with them but I'd think they were not hugely confident/skilled personally with control yet, much like the beginner skiers who end up coming into the lift areas a bit too hot and such. On ice though it's a whole other game, can still control things but for me at least I just have to take it agonisingly slowly and the shins and calfs start to burn from the effort of not losing it so most fun is removed from the activity.
I have never been on a snow board, but a question based on observations made over the past two weeks (including a chap on a snowboard wiping my girlfriend out by running straight into her from behind) - is the rider in control as the word is commonly understood, or are they providing very approximate suggestions to the board as to where it might want to go next?
