The feature where Firefox repeatedly changed your preferences and helpfully showed PDF with the JavaScript jank was pretty terrible. Changing that preference a third time won't make it any more charming. Yes, yes, the cattle are supposed to be OK with the "movement" of their cheese, move along now, nothing to see here.

Uh, no. Coffee in America started out cheap and for the masses (following some sort of Tea Party, I think it was) and then even more for the masses (now with pre-ground beans, instead of using the mill in the stock of your Sharps Carbine) and only very recently has there been a movement towards not-mainstream "hipster elitist circle" coffee made by purists.
> Things don't become worse
This is not what I've read; for example, British church organ making went through a rough patch around the decade of 1900 or so. With a little study of history more such examples could doubtless be found. One might even be optimistic that the modern web might pull itself out of the "big miasma"[1] that it has sunk into. But if the powers that be are blind to criticism, and go on about "tooling issues" or whatever, eh, it might be a while before changes can be made for the better.
By the way, Arnold Toynbee said some pretty funny things about blind elites.

This is not about ideals, this is about foisting crap on the world that literally nobody wants or needs.
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 try to fight the new order by disowning 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.
The 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.
