Didn't you read my entire post? More specifically, this bit:
*) You can't do anything about the security hole, in most cases, so you do not benefit from knowing that it's there.
"You can't do anything about the security hole, in most cases".
The nature of most security holes in Internet Explorer means that you cannot avoid them with anything less than not using the browser.
By releasing the information, Microsoft are allowing more 'script-kiddies' to exploit the security holes thus making life harder on Internet Explorer users.
And, like I said, with Microsofts longer time between finding a security hole and releasing a patch I wouldn't want to have the knowledge about the security hole floating around out there on the world wide web.
But I guess it's too popular to bash Microsoft to care about that.
