The other important parts are section 2, "Changes to agreement" and section 29, "Governing law and jurisdiction for disputes".

One option is that Namecheap considers this a termination "for cause" (because they no longer want to do business in Russia). If you disagree that that is a valid cause, you agree to resolve the matter in the Arizona, without the use of a jury trial (section 29).

Another option is that they consider this a "change of agreement" "in response to changes in the requirements of governments and administrative bodies, legislation and changes in the nature of industry"; in that case, "your exclusive remedy is to transfer your domain name registration services to another registrar".
