> WHY javascript code is even allowed to see all these actions of the user?
scrolling: used by games, maps, image viewers
link navigation: used for client-side routing (youtube/twitch, any website with a chat window)
text selection and copy/paste: word processors, spreadsheet editors, forum software, etc.
I'm not sure if your question was sincere or if you were trying to say that the web should not support these use cases.
Yes, you get to the heart of the problem - we turned what started of as a document viewer into a general purpose application platform.
Features paramount in a document viewer (broadly, "respect the user's local document viewing preferences") aren't desirable in a general purpose application platform.
A large number of companies/web developers don't think of themselves as offering the user a document to view on their own terms, but rather an "experience" that they want full control over (which means, most of the time: show ads and record user behavior).
If you're offering me a game, fair enough. But if you're showing me my hotel reservation or electric bill, I want a document, not an ""experience"".
Management wants you to want to have an experience.
nobody asked management.

On the extreme end, a web app can do all of its own rendering in a canvas with WebGL/WebGPU. Some apps do exactly this: Figma, Google Maps, Google Docs. Just to name a few. (edit: Earlier I claimed PDFjs uses canvas, but it does not. I was confusing it with Google Docs [1].)
It's a thing you can do. But it is very bad for extensions and extension developers for the same reasons that Java applets, Flash, and Shockwave were bad for the web. These apps are difficult for end users to customize. It's a real bane to tinkerers. And it's a shame that "view source" has slowly grown completely useless over the decades.

I’m glad the era of Flash games existed. I’m glad it’s now possible to do all the same stuff in standard JS.
Why are HTML5/JS games so much laggier and buggier than Flash games?
Maybe it's not due to differences in the technologies used. I can imagine it's because less people make these games and spend less time per game to optimize it. Years ago there were thousands of flash games of each genre, a lot of them very well made, likely optimized for speed, pure works of art. Now I see the same 100 HTML5 games on all the sites, maybe reskinned a bit. I don't think we'll ever have in terms of quality as what was available on Kongregate or Armor Games.
I might download an old browser with Flash and some games. Years ago there was a collection of a few TB of Flash games, hope it's still around. Maybe some games that required network will not work, but most didn't.

> scrolling: used by games, maps, image viewers
Out of curiosity, does anyone like the way Google Maps hijacks scrolling? I use a trackpad. When I scroll, I'd want it to pan around on the map, not zoom in and out (which always feels awful as a scroll action and never stops where I want it to).
Click-drag to pan doesn't feel nice.
It doesn't really matter anymore, since 99% of maps use is on mobile now, but this was always a small pain point to me in the past.
If you mean you prefer pinch/spread for zoom-out/in, I prefer the status quo with trackpad 2-finger scroll for zooming.
Pinching/spreading with index and middle finger feels unergonomic. Using my thumb on the trackpad would also feel unnatural, as would putting my 2 index fingers on the trackpad.
2 finger scroll is something you can "fling" such that the zooming motion continues even as your fingers have been lifted off the trackpad. Trying to "fling" a spread-out motion with your index and middle finger is an awkward motion, and of course in a pinching motion, your fingers would just crash into each other, so you'd have to lift before they crash. Pretty awkward.
On the phone, I often prefer tap then drag up/down (i.e. touch, lift, touch, slide) to zoom in/out with a single finger. It allows me to "fling" the zooming motion so it continues after I've lifted my finger. It makes a phone's interface behave like a trackpad's scrolling-zoom.
I never liked it either.
Panning by swiping feels so natural. That it breaks on a trackpad feels like a major oversight.
