Choosing not to allow renewals would have been been acceptable but they straight cancelled those domains prematurely before the term of registration had ended. Basically pulling the rug out from underneath people without giving them adequate time to migrate. Allowing domains to be sniped by unscrupulous parties who put malware on them which hurt many thousands of people (mostly foreigners who had nothing to do with Russia). Totally irresponsible and criminally negligent behavior for any registrar. I hope they get sued for for breaking their own contracts and causing widespread destruction via malware.
