sure, it's newsworthy when a giant ski manufacturer parts ways with huge-name athletes. but it in no way reflects Salomon's stake in the freeski market, their finances or their ability to support progressive riding.
ctownsend said, "There are individual reasons for each individual departure of Sammy and Simon," and I imagine that's exactly what's up. Sammy probably isn't that motivated by $ - he's making a shitload through other sponsors - and he probably wants a ton of freedom and very little pressure. From Dumont's angle, I'm guessing he could probably get more $ from Head.
Salomon remains in a really strong position. They have, by far, the biggest budget of any ski manufacturer dedicated to a team, and it's only a matter of months until Salomon signs the next big thing, the next kid to come out of the woodwork a la Bobby Brown, etc.
