Rambler filled copyright claim to @isysoev regarding @nginx, nginx office under police raid (unconfirmed). Originally posted by @igorippolitov , but somebody asked him to remove his post. pic.twitter.com/76mBNtV31G
Context: development started in 2002 by Sysoev when he was Rambler employee (as sysadmin). Rambler never claimed copyright on nginx. Later Nginx Inc. was founded to provide commercial services. This year @F5Networks bought Nginx Inc., and Sberbank bought 46.5% of Rambler Group.
