Yes, it's done, as it is with many stocks, when an MM wants to make a deal on the long side for, usually, a high volume client, but can't access the shares. Rather than tell the client they don't have the shares, and possibly lose the client for future deals, the MM will borrow, i.e., short, the shares to provide them to the buyer. It's not the same mindset as someone actively betting against a company.

There are a lot of reasons why SFOR share price will ascend, but shorts getting fried is not one of them.
