Not at all. Imgur does the passive side too. And by number of operations, it is by far the biggest one.

Without user-generated content there is nothing to host. And in any case they long ago turned from an image hosting site into a social media site. There's reactions and commenting as a core part of the service now.

So what? Without the passively-read content there'd be no user-generated content.

It is totally optional.
