Earlier quoted context omitted.
At this point my mobile experience is go to website, read a couple of sentences, watch javascript muck with the layout as you describe, then a full screen popup wanting me to register or download the app, followed by a part of the top of the screen with a app store link for the app, then I get to read the article - maybe. I think we need something that is to websites as markdown is to word processor files.
I'd like a browser that just removes all the CSS and JS and gives me simply the text, like Safaris reader mode, but without the need to ever leave it.
Or worse, unmangled text in JS source. Or text that's set to display:none until the JS gets to it.
If you're going to compile things clientside (looking at you, markdown), at least put the raw text in something the browser can display before the JS compiles it.
