As far as I'm aware, no ".ru" domains have been seized yet from media independent from the Russian government. Instead, they prefer to block website access - by law, every ISP has to install DPI-enabled hardware, which is used to censor the net.
I confirm that the the link doesn't open from Russia.
I'm aware of one - grani.ru had to become graniru.org a few years ago.
Why seize a domain when you can just block it country wide?
