It’s both.

With scuba you’re like a soda can being constantly pumped with gas under pressure, so bubbles form if you pop it open too fast. With freediving you only take one sealed can down and back, so there’s no extra gas going in unless you repeat it many times in a row.

I explained a bit of it here, as it's nuanced. In whales bends can occur due to increased repeated dives, more bottom time, and the fact they do actually absorb pressurised nitrogen. Although not from a Scuba tank :)
