Earlier in the week a blog post by Nokia engineer (and former Microsoft employee) Justin Angel highlighted a number of issues with applications from the Windows Store that enabled, among other things, the unauthorized conversion of trial apps into full versions, the modification of the prices of in-app purchases, and removal of embedded advertisements. Soon after publishing his post, Angel's blog was knocked offline in a flood of traffic; at the time of writing it remains unavailable, returning 503 error messages instead of content.
