...what? The web is better than most native platforms in these.
The web is accessible. It has many features for screen readers and such, but more importantly, it is inherently flexible and allows content's form to be adapted to the reader's needs, thanks to the separation of content from style. A single web page, unmodified, can work on a desktop PC with a mouse and keyboard, a capacitive touch device the size of your palm, a stylus-input device the size of a laptop, a printed page, a screen reader, a ten key mobile phone from yesteryear, and more. The web lets users define custom styling that meets their needs, lets users selectively remove content (ads, for example), etc. No native platform is that flexible. Yes, some sites break screen readers, but this is true of native apps as well.
The web is incredibly embeddable. Any web page can, with one line of code, incorporate any other web page, and it "just works". You simply can't do that with native apps.
The web is composable as well. Sites can load JavaScript from each other very easily.
The web also supports resource sharing in various forms, but people don't necessarily use them.
Indeed, Electron already is starting to provide these kinds of facilities. For example, it allows you to load native node modules, and it provides some tools for integrating with the desktop envirionment (see https://github.com/atom/electron/blob/master/docs/tutorial/d...).

I knew I wasn't the only one who loves this pretentious diaresis style. Stay strong, brother/sister/sibling. Stay strong.
I guess if that demographic did, there would be less "unix philosophy" cultism, as the efficacy of the unix shell is merely on par with that provided by other relatively coherent software toolsets. The shell is really pretty barebones compared to the rich semantics provided by many toolkits and object systems on which user interfaces have been built: GObject and NeXT are two modern examples.
[That said, where shell shines is by providing so few abstractions that virtually any garbage has the same semantic depth as things which were designed to be used in the shell. Bytes are universal on the common computing substrate.]
The web, on the other hand, is a platform "designed" by the erosive flow of eyeballs during the 1st-nth browser wars, without much of a direction beyond tacking on additional pretty features without breaking backwards compatibility too much.
Attributes like a11y, embeddability, composability, and effective resource sharing tend to simply fall out of well-designed platforms. The web has an effective answer for none of these desirable concerns. Look at how screen readers break on js-heavy and dynamic web pages, the ongoing security disasters of XSS and iframes (and the complexity of login services like Facebook's/oauth/openid), the disappearance of Google reader, and the half-assed way CDNs offer partial, ad-hoc offloading of some resources via surrender to centralization.
