Why doesn't Sina constellation update?

The reason why Sina constellation is not updated may be:

1. Sina has no server resources to continue to provide this function.

2. The relevant personnel of Sina Company have left their posts and cannot be maintained.

3. Sina no longer thinks that this function is in line with its overall goal.

Sina didn't get enough benefits from this function, so it can't continue to support its maintenance.

5. The number of users is too small, which causes Sina to stop investing.

6. There is a technical problem with this function, so it cannot be maintained.

7. This function has lost its competitive advantage in the competitive environment.

The above are possible reasons, and the specific reasons need to be further understood.
