Mirabilis created ICQ. AOL bought Mirabilis in 1998. Russian investor DST (which soon became Mail.ru and later VK) bought ICQ from AOL in 2010, probably because Russians were among the few nationalities still using it. Russians were over 25% of the hits, and it was the biggest instant messenger in Russia at the time. They also own VKontakte, hence why they're directing people there.
