Why is Celsius paying-off debt?

Of course, lowering the liquidation price for their WBTC. I got you! But, this was important when liquidation price was around 20k.
Now it's <3k, and they're still paying off debt. Anyone knows the reason for this?

How is this seen in the light of a potential bankruptcy? You are not allowed to choose, whom you pay off and whom not, when filing for bankruptcy.
It does not make really sense to me.
