They (noip.com) had zero pre-warning of a domain seizure. Regardless of any literature you dig up from years ago that states some botnets use Dynamic DNS services such as noip.com, it does not mean they had warning they were about to be seized. Others have commented that the court order forbid anyone, including Microsoft, from informing noip.com prior to the seizure.
It should be noted, that most/all "cloud" services likely have some sort of illicit behavior being conducted through them... Ec2, Azure even, etc. Botnet's use the same services me and you do... that does not for even a second make noip.com responsible for the botnet's actions.
