Microsoft is NOT going to commit resources to "deprive Google from air",
as they illegally (but with relative impunity) did to Netscape.
Microsoft has more urgent and immediate problems. They've looked over
their shoulder and seen a pack of Lunux wolves snapping at their heels,
intent on cutting the Microsoft Achilles Tendon, monopoly pricing power
is vanishing (today you can buy an upgrade to XP for $29.95 and the
vision of Longhorn get pushed over the new products horizon---far, far
out of sight.
