How Serious Is Hacking In Mobile Games?

As a developer contemplating trying out the mobile game scene, a GDC session about hacking/tampering looked interesting — but I wasn't able to attend. The presentation isn't available online, but it was paired with a whitepaper [contact details required], which can be downloaded. I'm surprised by some of the information presented and the potential for damage/mischief. Not so much that these issues are unheard of — they've existed for years on other platforms. What I find surprising is the lack of support at the OS level on mobile devices to defend from many of these types of hacks. Have we learned nothing from the pains of the past? How significant are the points about hacking/piracy in the mobile space that are discussed by this whitepaper?
