MS didn't 'kill the browser competition'....
...Netscape did by deciding to charge $30/ £30 a pop for what was previously free.
In a similar vein to Apple having the option of crushing Windows back in 1990 - 1994, but decided to go for the $$$ instead (and still are, one could argue).
The two above facts seem to be forgotten on a regular basis, by journalists as much as anyone.
And MS introduced several options that, previous to IE6, simply weren't available - Outlook Web Access seemed quite advanced in 2003 because (for example) it could notify that mail had arrived without having to refresh the screen. No-one was bleating about standards back then.
MS have a history of trying to adopt standards to their purposes, or inventing new ones while the rest of the industry squabbles (like they still are about network speed auto-negotiation), so none of this article is really news....but then, there would be no article :-)
