Replying to Why do ski brands tweak the design of very popular models?

I am genuinely curious and uninformed, no hate intended. I get frustrated when I find an all-around great ski that myself and many others absolutely adore (looking at you 2017-18 ON3P Kartel 108’s), and then a year or two later it’s discontinued or the design is changed and I’m left thinking about how awesome it was.

If a ski is so wonderful and rides just about perfectly, why does it need to be changed? Why can’t it just stay on the market forever so I can buy a new pair every other year? Obviously the perfect ski is subjective, but the k108’s, for example, were just so fun in everything. (Source: me and my friends I guess)
