Panic is, ironically, a "moral panic" type of company. When e-culture shifts, they shift their policy accordingly. I would not trust them for stability.

What do you mean by this? What has Panic shifted on? The only example I can think of where they've shifted on anything is they released Transmit for iOS, then after a while they discontinued it, and that's because it simply wasn't making enough money for them to justify the cost of maintenance.
