While that is true, the missing part is the following. As I understand registration process in zone .ru / .рф is done by a russian legal entity (Coordination Center for TLD RU) and under the jurisdiction of russian courts. As a citizen of Russia I can say that russian courts are far away from the Rule of Law and under the strong pressure of russian government. So, even if the actual website may be hosted anywhere, russian court may make a decision to take back a registration and, theoretically, the row in DNS may be replaced (the link will be the same but may tend to a different, potentially unsafe hosting). That is the risk that I see.
It is the same question as “What are trustworthy countries” imo
