Yes, dpi has great, useful applications (ddos mitigation and other
security, for example).  And it has bad / harmful applications
(dictatorships doing dpi to catch political dissent).

That says a lot more about inappropriate / appropriate use of dpi
rather than dpi itself.

Nothing at all in DPI that makes it wrong, deeply evil etc.

Which is why the political debates over it bother me. Declaring dpi as evil and regulating it could very well limit security of the future; not to mention the fact that DPI tends to be extremely vague in definition dependent upon its implementation.
