I see what you are saying and you are right in some regards. But, I think big companies are also very actively involved in the community as well.
First, I don't think the CEO of any of these bigger companies is necessarily the one making all the decisions. The CEO of a bigger company isn't going to be making the decisions on events/competitions that they want to endorse/put on, or what athletes they want to sponsor.
Also, while the CEO of larger companies probably aren't be active on NS, it doesn't mean that several other people at the company aren't. Take K2 for example. I know there are several people who work at K2 on here all the time. Ryan Schmies, for example is very active in the community, and has addressed problems or concerns that I have had before. I think that the people who work at these larger companies are still, for the most part, very passionate about skiing and the community.
Same thing with onenerdykid, he is the Boot Production Manager at Atomic, and is very active on NS. He frequently helps those with questions. These are just the only examples I can think of off the top of my head.
I don't really have a preference one way or another, I have had "smaller" company skis like Bluehouse and 4Frnt (if you can even consider that a "smaller" company anymore), and have had bigger company skis like K2 and Rossignol.
I'll probably get roasted for this response but whatever. I just think that these larger companies might get unwarranted hate.
