As a GNU Maintainer for glibc I have some visibility into the tickets
filed for FSF copyright assignment to glibc.

For the record both Open Mobile Platform LLC and Evgeny Eremin
have FSF copyright assignment on file for glibc. We can accept any
and all patches. Thank you all for your patience with the CLA process.

I can also confirm (and sorry for not responding more quickly on the
other thread) that all discussions between Open Mobile Platform LLC
were had with *@omprussia.ru accounts and the FSF Copyright &
Licensing Associate as part of ticket [gnu.org #1543679].

In this case *@omprussia.ru emails are by default considered to be
employees of Open Mobile Platform LLC for the purposes of the
copyright assignment, but we all know that might be inacccurate and
we trust everyone to maintain correct protocols for copyright
assignment.
