Microsoft is displaying ads in yet another of its apps; Windows-maker gets sneaky in mobile Outlook
There's no such thing as a free lunch, and there's no such thing as free software (well... very, very rarely). If you don't pay a monetary price for software, you're almost certainly going to pay for it with your privacy, or by seeing ads.
This is something that users of Microsoft's software have had little choice but to become increasingly familiar with -- even in the case of paid-for software. The latest of the company's apps to fall victim to the advertising plague is Outlook Mobile. Users are particularly annoyed because the ads are difficult to distinguish from emails.
