With regards to who is selling the $5 calls, it can only be the MM I believe. There is definitely something strange going on, but only the MM can control the stock enough to accumulate enough shares to cover all those calls.
Everytime the shorts keep hitting the bid, trying to force us down they use 100k+ and barely drop us because the buying pressure holds up. I think most institutions are wating to buy until after the 10K comes out to be safe and at this point retail is either in or out already.
That's why I think it must be the MM and while I originally thought it was smart shorts getting out, I'm more inclined to believe it is now big money(in the know) that has the MM pulling the strings, because the shorts never stopped hitting the bids and history has shown with this stock that when the shorts try they do manipulate the price. But this time the MM is soaking up all the shares for the $5 calls.
