1. Cover *could* fire Sana for failure to deliver sufficient content.
They chose not to because if they hire and fire too often, that damages the image of the company and makes them look incompetent. Poor judges of a talent's worth and future earning potential and all that.
2. Sana auditioned well, but then failed to live up to initial assessment.
3. Auditioning and developing her design and Live2D model, and manufacturing merch may be a considerable investment. Sana may be poor ROI presently, but it is possible that she will deliver down the line, and Cover likes to think long-term.
4. Sana actually is in agonizing physical pain on account of her enormous IRL booba's gravitional pull on her spine and it is a stipulation of her contract that she forgo breast reduction surgery because Cover mgt are men of culture who would never permit such a crime against humanity.
Also it would look really mean of them to fire cute brown girl for having stonking great tiddies.
5. Human milk is actually more valuable than we know and Sana is Cover's true cash cow and solution to world hunger.
