While Overloud and AAS have kindly allowed to use what people can use now, and that can be just a nice gift (which cost them a bit of time to prepare, keeping there labels inside your new DAW, so make sense from marketing perspective as well),
all other (Steinberg, Magix, Presonus, etc.) are here to simply grab your money (except Presonus, they do not even have "special" prices for you...). So LOL to everyone who think they are responded driven by any other reason
Cakewalk has already declared that in case they stop servers, they will issue not expiring offline installer. That close the question about Sonar itself.
I think that CW should:
* unlock Adaptive Limiter. New plug-ins was a big part of "new features". It is clear that Drum Replacer and Vocalsync are Sonar specific. But this one is not. It was not declared as a "light version".
* return Z3TA2 to old authorization. It was sold with one authorization but "updated" (just bug fixes) to another. Sorry to say, but that is BS.
I think that CW may:
* unlock Rapture Pro Session, if it is locked (the same reason as Adaptive Limiter).
The rest I guess was not locked or can not be unlocked, till original authors do this (as Overloud and AAS).
