I would accept adobe's subscription model. I use it now. One does not get something for nothing. Software and software upkeep costs money. That is one of the lessons of this whole debacle. If Sonar goes somewhere else - it is worth paying X$ a month to keep it maintained and keep the staff properly paid.
This is not going to happen.
Adobe already has Audition which fulfills their needs and SONAR does not fit at all in Creative Cloud catalog.
If SONAR went to Adobe: would Cakewalk users accept Adobe's subscription model? -No.
