EDIT: this was largely just to strengthen one of your points.
Every single time something becomes big, the hardcore early fans of that thing will complain about the change.
This used to happen with bands. Early die hard fans enjoyed having their own tribe or clique built around the band, and then when the band became too successful they'd say that the band "sold out" and that the newfound fans aren't really fans and so on.
This happened with Linux where many people say Linux isn't fun anymore, or they lament that everything changed. I was an early Linux user, but I find that Linux is better than ever and I'm thankful I don't need to configure X anymore.
People of the early internet were in their own little clique, and then the entire world jumped in and they lost "their place." They will always lament this change, and they will always say it used to be better.
Humans are tribal and they forms tribes around anything and everything. Anytime their tribe is displaced they will become resentful even if that displacement makes the thing their tribe formed around better in every possible way. For me, I never had a solid sense of "tribal belonging" and therefore never really cared about these things, but I do understand the impulse as I get very vivid and strong experiences of it at sporting events, concerts, and so on. I suppose the strongest sense of tribalism I feel consistently is that of being a contrarian by impulse, and I feel some kind of kindred spirit with other contrarians... so maybe take everything I've said here with a grain or pound of salt.
