Microsoft will cripple Chrome and Firefox on Windows 8 arm tablets. Who cares?

When arm tablets running Windows 8 ship, Chrome, Firefox, and other browsers will be at a disadvantage, because Internet Explorer is the only browser allowed to take advantage of some features of the operating system. Mozilla and Google are crying "foul". These restrictions really cares?

To understand the controversy, you need a little bit of background on how Windows 8 on arm tablets. (Windows 8 on arm tablets, once called WOA, is now formally called Windows RT.)
RT of Windows, such as Windows 8 will include an interface and a desktop interface and some call it the desktop interface "Windows Classic". It is likely that most people won't run the desktop interface that often, because the metre is much better suited for touchscreen tablets.
The Metro is a much more limited than Windows Classic, and a variety of technologies and add-ins will not run into it. This is true in the traditional version of Windows 8, as well as the compressed version of Windows 8, Windows RT. In the traditional version of Windows 8, however, any browser will be able to run in the desktop, taking advantage of certain features.
Windows RT, though, just a browser will be allowed on the Windows Classic desktop-Internet Explorer. Chrome, Firefox and other browsers will be banned. And this is what Mozilla and Google has weapons. (Or is that?)
Project Manager, responsible for Mozilla Asa Dotzler from Firefox development for Windows 8, said in a blog post that this gives Microsoft an unfair advantage:

"Windows on arm prohibits any browser except Internet Explorer running in privileged environment" Windows Classic ". In practice, this means that only Internet Explorer will be able to perform many of the functions vital for the advanced computer modern browsers in terms of speed, stability and security that users have become accustomed. Given that IE can run in Windows on arm, there is no technical reason to conclude that other browsers can't do the same.
Why this is important for users? Simply because Windows on arm-designed as currently restricts the user's choice, reduces competition and innovation of chills. Allowing only IE perform advanced functions of a Web browser, third-party browsers are effectively excluded from the platform ".

Google agrees with Dotzler, telling CNet:

"We share the concerns that Mozilla has raised regarding Windows 8 limiting innovation and user choice. We have always welcomed the innovation in the browser space on all platforms and I firmly believe that all of us have great competitors do work harder. In the end, consumers and developers to benefit the most from tough competition. "

Microsoft claims that it needs to restrict access to desktop for reasons of security and performance, and this is why only certain applications gain access to it, specifically IE and Microsoft Office.
Do not buy Microsoft's reasoning fully--after all, Windows 8 on PC, other applications are allowed to run on the desktop. It may be true that RT Windows hardware will be more susceptible to performance slowdowns that traditional Windows hardware because hardware RT will generally have slower processors and less RAM. That may not always be the case, however, because Windows 8 will run on netbooks, which typically have low-end hardware.
However, I don't think that banning Chrome, Firefox and other browsers from the desktop RT will make difference in browser market share. There is not much more than a chance that Windows 8 tablet will make significant progress against iPads and Android tablets. And people who use Windows tablets, only a very small percentage would likely change their default browser, even if they had a choice. So in terms of market share, not allowing Firefox and Chrome on your desktop will be barely registered as a blip.
Regarding the user's choice, certainly it would be better if buyers of Windows 8 tablet has had more of a realistic option in the browser. But limiting the choice of browser is likely Microsoft hurt more than help it.
