The point is not that GMail gives you ads and Microsoft does't. You get ads on BOTH services. The difference that Microsoft is pointing out is that Google is mining your e-mail to sell their advertisements. That's true. It's not "low" for them to mention this.
You get ads in Outlook.com/Hotmail.com as well. However, MS is targeting the ads there from your Bing searching habits and any info provided at signup.
