The bigger issue is that it's basically just well hidden fees. You can add a decent amount of income to your portfolio by lending out the stocks to short sellers. Particularly in a market crash, the fees for borrowing stocks skyrocket (can easily be in high double digit %). Good firms allow you to lend out your stocks and give you the fees. Less good firms claim to give you a very cheap deal, but then basically shaft you by claiming these benefits for themselves.

If this business proposes to be profitable by harvesting the borrow fees, then them being cheap is really disingenuous because they give you with one hand and take from you with the other.
