The new model may point to what was wrong with the old one - in that the world has changed around it and it has been left behind, forcing them to change to protect their ability to make a return on their product. In having every copy call home once a month and disabling itself if it's found to have not been paid for, it may suggest that the torrents and file-sharers of cracked versions were very much taking their toll. I have no figures, but if there were an illegally downloaded free copy for every legal version sold with cash money, that has in effect just halved the value of every kosher copy sold. Take that sum and apply to real world figures and it may have been looking like the old model was collapsing around their ears. As you say (propper) business always had paid for it and this new model very much suggests to me that the gains provided by selling to amateur and non-business users were being very much outweighed by the losses caused by the ease and speed of file sharers cracking the authentication system and releasing it to the world for free. Adobe has not cut us off from their goods by any means, we can still pay for a copy but in a different, more business friendly way, suggesting that the non-business market has very much lost its appeal in the face of illegal downloading. That's the way I see it happening, anyway. Adapt to survive, it could help the company no end as long as hackers don't find a way of cracking the call-home system... And also if business users can out up with the huge flaws of the initial releases and new system issues... But with updates happening as and when they choose, they could adapt and update that system along with its authentication every three days making it very tricky for any underhand activity.
