Is Apple stifling progress in Web standards?

Isn't the Web a competitor to the App Store? Especially when web apps start to catch up with native apps (and Santa tracker and the rest of Google's Polymer apps seem to suggest this is only a year or so away, and FirefoxOS has certainly made huge strides in this direction) and offline support with web workers is ubiquitous?

My experiences with Web Components, at least, do seem to suggest they're not very proactive and/or dedicated in the standards department, at least. They did put Shadow DOM into their spec at one point, but then removed it. The template tag is in at least, but that is a very, very simple tag (inert content until added to dom).

(I also found IE11 to play much nicer compared to Safari as compared to bug in my apps, not standard support, although that is really an indication of IE11's quality rather than Safari's laggardly standard support.)

As a BS excuse?

Or Mozilla and MS refusing to implement Web SQL Databases because IndexedDB and NoSQL was better, even though one works on all mobile phones since 2010 and the other is wonky and has a terribly designed API.

No need to single anyone out. They're all equally guilty.

The dream of the modern web is the concept of a single standard/platform that is used for all user facing software. This is a flawed idea and this article demonstrates one of the biggest reasons for that. By definition, features only become part of open web standards if all the main players agree to them. All the players have financial and political incentives to block various things. Corporations can block something that you want to use even though you have no relationship with that corporation. In a capitalist system you have very little leverage against a corporation that you have no financial relationship with. What are you going to do: stop buying the [Apple/Google/Microsoft] products that you already don't use? What's left is people writing angry impotent blog posts against companies that don't care about them in the least.

The list of proposed standards that have been blocked/delayed by one of more of the big browsers is huge. Blocking proposed standards isn't uncommon, if anything it's the norm. mathml, websql, pointer events, h264 video, nacl, flexbox, webgl, jpeg2000, webm, mp3, ogg vorbis, theora, webp etc etc.

Because of its origins as a way of displaying untrusted documents the web has no 'escape hatch'. It's a very tight sandbox. Flash and Java used to fulfil that role but they are on the way out. The web has a very basic trust model - all pages are untrusted and there is no other level of trust available. So if what you want to do hasn't been blessed by all the browser vendors then you are screwed. Does one of the main browser vendors compete with your product? It's quite likely that they do. Yet you want to give them full control over how your code can run all on all users machines?

If you don't like the idea of a corporation being able to veto a web standard then you need to seriously ask yourself if you actually like the idea of open web standards at all. Political vetoing is integral to the idea of open standards created through consensus and it isn't going to go away no matter how much people fantasise about it.

To be fair, if you compare IE11's with other browsers at the time of its release, they have stellar support. There is still no other stable browser that supports let, and the only other browser with support for const is Firefox 36 (released yesterday).

For better or worse, Internet Explorer has a far longer release cycle. But right after release IE is often ahead of the other browsers in some regard (CSS calc and the ECMA Internationalization API come to mind).

Safari hasn't done that in a while.
