This is exactly what "trying not to discuss Ukraine" is. Without outright banning it. When subreddits create a mandatory megathread, it is always with the purpose of kneecapping that specific topic. Putting a large topic into a single thread makes sharing information about the topic extremely difficult. I'd like to add that there's no reason to believe that such topics that get buried into megathreads would have taken over a subreddit otherwise. The news cycle turns. For example, worldnews today would look no different if the Ukraine war topic had been allowed to breathe. At most it would have caused the minor inconvenience of going to page two for the fraction of people not interested at all in the Ukraine war at that time.
