I don't know where you went to school, but you should ask for a refund. Or read up on basic percentage calculations.
Microsoft claims that 93% of the malware traffic is traced to No-IP. But that says nothing about the total amount of traffic for No-IP, nor does it say anything about the total volume of legitimate domains. Malware traffic could be as little as 1% on No-IP's infrastructure while still accounting for 93% of malware DDNS traffic.
It is completely wrong to state that 93% of No-IP domains are hosting malware. A large number of legitimate customers are being affected by this, and Microsoft is not resolving their DDNS domains correctly (as promised). The actual percentage of legitimate vs malicious domains is unknown, as is the distribution of legit/malicious traffic.
Also, Microsofts claims are disputed by No-IP, so we should not take them at face value. No real evidence of malice has been proven (yet), which makes it extremely questionable that this was conducted ex parte.
Finally, the fact that No-IP was a favorite for malware is not (or should not be) in itself sufficient to take control of the domains like this. I sincerely hope Microsoft can prove No-IP did not respond properly to requests. Or that they can document that an extremely large portion of total traffic on No-IP was malware (which we know nothing about at this point).
Simply quoting the 93% number is a pile of BS. I can't stand by itself. I can say with certainty that at least 93% of the Nigerian scam mail I have received the last year has used a hotmail.com or outlook.com account. But surely this does not prove that Microsoft is willingly aiding Nigerian scammers and that their domains should be seized?
