I enjoyed Panic's polished applications since way back when but the way they simply drop paid for apps with an existing userbase due to "lack of revenue" (Status Board [1], Transmit on iOS [2], Unison [3] and Audion [4]) really left a sour taste in my mouth.
Transmit for iOS was a particularly big loss for me, so much so that I personally am going out of my way to avoid their products.
