Simply put, Short Sellers have for decades made the argument that disclosing their position makes them a target for Short Squeeze. However, they in many cases target legitimate companies with the sole purpose of attempting to "shake out" longs to make a profit. This is not the intended use or purpose of allowing short positions, which as I understand it is as a way to address fraudulent statements, find a companies true fair value or transfer of monies when a company is struggling / failing.
