In case you were unaware: depending on if your Canvas admin 'locked' this feature option to be on or optional, you may be able to disable it. Take a look at the course Settings > Feature Options > to see if you can uncheck Discussions/Announcements Redesign.

ps. re: measures of sanity...  there are quite a many things going on in this clown world which I've observed as of late which sometimes have me thinking I am in some sort of Truman Show. As we know, the message there is to keep fighting against artificial narratives... 😉
