Don't blame Adobe. Blame the customers that support it. As for me, I'm still on Photoshop CS6.
I don't feel the need to blame anyone. I too am still using CS6, but don't doubt that eventually Adobe will offer some very significant(can't do without) improvement that will force me to the cloud. Thus far, not tempted.
As for camera makers, it's an interesting (and frightening) idea that, in future they may offer cameras whose feature set is intentionally missing desirable refinements. They could then offer subscription firmware updates to add features. It would provide a revenue stream from owners who cannot justify the cost of moving up to the next generation camera, but who would gladly pay a fraction of that cost to upgrade their current camera.
