Ukraine has (had) a vibrant developer community. The war has made many folks switch from the IT side to the military. Do you know of any Open Source projects that are at risk of being abandoned because their lead dev / maintainer has left to fight (with a risk of never returning)?
Sergey Poznyakoff is based in Odessa, and maintainer of a couple of high profile GNU projects: https://gray.gnu.org.ua/project/list/
(tar, cpio, pax, mailutils, radius, gdbm, ...)
he is still committing on GitHub during the war, so looks good for now.
then there are Blynk and PlatformIO based in the Ukraine (Kiev), essential for embedded.
Grammarly has not that much open sourced, but they are huge.
