The pressure of water at 3000 meters is 4268.33 PSI, and whales have been actually observed there. I don't see how sustaining 30% more pressure than they've been observed to do is an insane idea.
Submarines don't have the option of getting rid of all the air - the crew would die. Whales can exhale the air in their lungs before a dive, and the rest of their body is largely non-compressible water.
The very article you're citing even shows where your logic is failing:
> very significant because the Komsomolets had to "defend" a much larger air bubble against the encroaching pressure of the surrounding ocean

Whales have minimal or no "air bubble" to defend.
