As @TravisJ pointed out in a comment, Stack Exchange is owned by Prosus/Naspers, the same company that is the largest shareholder of VK, the biggest player on the Russian internet market.
Stack Exchange may want to address whether this has influenced their decision to not condemn Russia or show support for Ukraine in any way that is visible to people who visit the site.
UPDATE:
Prosus has announced on March 7th that it is selling its share in VK, after VK's CEO Vladimir Kiriyenko was placed on the sanctions list. Naspers still owns Avito, Russia's largest online marketplace, valued at $6 billion before the Russian invasion of Ukraine. (Prosus and Naspers are twin companies with a "cross-ownership" structure, both run by the same people.)

RE: COMMENTS
Owning Avito and 27% of VK is not a tenuous link to someone who knows someone who knows someone, but a huge business interest. Asking whether this has influenced Stack Exchange's decision-making is not a "conspiracy theory", but a request for clarification.
(And again a number ofI'm replying here because my comments have beenkeep getting deleted, making it difficult to follow the conversation there. I don't know why moderators insist on pruning the comment section seemingly randomly.)
