Why? Are we not doing enough?

If there are no users, there will be no new contents added.

If there are a lot of users (many more than there are now), there will be enough people around to support all sorts of niche communities, like Reddit had.

Active user count is probably the single most important metric to whether a platform is successful and stays alive. Even above quality of content, as proven by many other social media platforms that thrive despite being flooded with trash content.

No one wants to hang out in a ghost town.

As a Lemmy shareholder, I'm outraged. If Lemmy doesn't get more users soon, I am going to stop the thrusters that keep the world turning. You have been warned.

It just signals that this platform is flawed to the point where it's bleeding to death. Keep in mind, a bigger userbase = more active community = better platform.
