Phoronix: Several Linux Kernel Driver Maintainers Removed Due To Their Association To Russia
(www.phoronix.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

IANAL, but I think the general answer is no. When someone contribute code to an open source project, although they aren't giving up their copyright, they do grant the recipient (and the rest of the world, for that matter) a license to use their code. In case of Linux, this is the GNU Public License. Unless GPL has a section about license revocation that I am not aware of, you won't be able to take your code back.
So I think good luck for foss movement. Hopefully, forking that project won't be illegal because otherwise foss will die
