I read the original e-mail as asking for something more than implementing recent sanctions. I hope and assume that the WMF has already taken the necessary steps to ensure that its activities are in compliance with applicable laws.
I agree with Gerard that the WMF is different from Facebook, and its mission may make taking steps beyond those required by sanctions unnecessary or undesirable. I know there is a BDS-esque movement afoot against Russian interests, but "are you now or
have you ever supported Russian interests" is in a category of questions that the WMF should very carefully consider before posing to any party. What may make sense for major corporations may not be appropriate for non-profits with an exclusively educational
and explicitly global mission.
