Wouldn’t it be easier to put “fins” on the iceberg? And just adjust them as needed, the same way you do a J stroke on a canoe?

Perhaps.  We could imagine thousands of devices with individual vertical pivot shafts that move together like the vent control on the air conditioner vent in your car.  Anchor the iceberg longways with the current as before, then use the multiple rudders to try that stepwise rocking motion sideways to the current.

Any scheme that seems plausible so far involves anchoring to the sea floor and using the existing current rather than trying to propel against it.
