Which is just one kind of subscription. You can't say the same for the subscription for cable can you? Or phone, IP? Isn't the software you're using to write posts here in a way part of a cloud and subscription and stops working for you the second you stop paying that subscription (for internet?). Adobe isn't taking away the files you create so the move to phone analogy doesn't wash.
Thought I covered some of those.
Cable - I can go from Time Warner to Local phone provide (ATT, Verizon). I can get service via phone.
Phone-talked about that...numbers a portable. I like iPhone, but Android is reasonable alternative.
Write Posts - IE, Firefox, Safari, Chrome, multiple phone apps.
Adobe is not taking away the files....RAW, because I still have the proprietary RAW, which others can work with....not having converted to DNG and thrown away the original data. TIFF...because it is a standard....but only the flattened TIFF....because many of the layers and filters are proprietary to PS CC.
BTW....YOU used the phone analogy....I was responding to it....forget that?
