Then this thing starts becoming profitable in the sense of bringing street cred and money and new kind of people rush in with their new ideas how to use this new thing. These new people don't share the same ideas with the original believers but they know how to build machinery around it to make it profitable and appeal for the masses. The new thing that was supposed to change the world becomes a concentrated and optimised version of the things before it.
The believers then become bitter purists and try to fight the new order by disowning the current technologies or methods and cater for the niche hipster elitist circles when the rest continues do their thing.
You can see it in everything, you can see it in printing press you can see it in Radio, you can see it in TV, you can see it in things that are not media: cars, clothing, shaving, coffee - everything.
Things don't become worse, they just become mainstream and that mass adoption is run not by purists but by people with no regard to the original ideals of the technology and masses love it this way and stays this way until its made obsolete by something else.
