If anything AS would absorb SF as AS development is leaps an bounds ahead of SF. We would see a complete re-vamping of SF and much of it would then actually work. You would also likely see a single license fee for all the included modules instead of the money-hungry fee per module you see now.

Yes, but the two things SF has over AS is the better UI and credit card purchasing, and potentially a larger user base, so it may make more sense for SF to be front-facing with AS providing the back-end and stronger coding capabilities. AS being down is probably just a coincidence.
I'm still have difficulty imagining that SF, after all this time, figured the DRM out. More likely they purchased the capability. Who better to buy from then AS, and why wouldn't AS not want a cut of SF revenue. If that was the case, we would likely never hear of it.
All we can do is speculate at this point.
