Now that "we should all stand together" (which I totally disagree on; we should all stand at least 1.5 meters or 6 feet apart), a lot of us are fighting for our lives, our jobs or trying to entertain kids that are no longer welcome at school / day care due to lockdowns.
In other words: I am sure some of us would love to create content (like myself), but they have a serious lack of time.
In other cases, people have just moved on, either to other hobbies or the rail yard in the sky.
