If you are looking around with several software vendors then you see everywhere this kind of structure popping up. The problem is that everything is already written, there is not really completely new software. Sounds may be strange, but it ends all in a few models which are around from the beginning. So the earn-model is drying up, people and business buy once a program, register it and that's it. You could see that with Windows. So now the next thing is that you can't buy it anymore, but you have to register and pay every year some kind of fee, like it was a magazine. Its already done with Windows, Office in different forms, Java, only OpenJDK is still free, but for how long? Next QT and after that the next firm which see its income going down. The question will be if this is a bad thing?
