However the output of the american media in the 2000s and 2010s, a media that is heavily influenced by capitalism has definitely shaped the internet and the worldly culture into its current form.
The internet is an amorphous mass of people, yes. But in the earlier days not everyone participated like you are "programmed" to do in our current society. Comparisons could be made with the early aviators or sailors, it is true that these things existed and were new in their relative eras and that everybody knew about them. But that doesn't mean everybody felt the need to explore these technologies. So, as the type of people changes that usually uses the internet, (from students, software people and mostly male teenagers that have an urge to explore it, to more corporate people and just about anybody) the content also naturally changed and the mental/emotinal rewards those original people once got when they visited 'teh intehrnetz' are not the same as they once were.
Look at a game like Utopia for example (you know the old browser based strategy game that was created by mehul). It was all about calculations and working in synergy with other people from all over the world (also somewhat about backstabbing, abusing and hacking of course). It was one of the bigger online browser games there was back then. If you compare to current online games like farmville and candycrush it's nothing the same and the types of people are nothing the same, why? Because it was different sorts of people that usually browsed the web back then. So yes, there was and has always been an original culture online that has gradually been merged with the mainstream people which has evolved internet into its' present form, and I don't disagree or agree with that, I just state it as a fact.
