Brad, I think you are seriously confused about what a MM can and can not do. Their role is to add liquidity to the market. They do not have to borrow shares to establish a short position, because they are Market Makers! I suggest you do a bit more research on this subject.
If a retail trader wants to establish a short position, the broker must find a source of shares to borrow. At the moment, Interactive Brokers is showing that there are shares of FSPM available to borrow.
I don't believe that placing a GTC sell order on your position will affect the ability of a broker to borrow your shares. It certainly won't affect the ability of a MM to establish a short position.
