For what you are paying, they do offer a pretty decent product & you always get the latest version, but when you think about it, you end up spending at least $120 USA per year. It adds up to a lot of money as the years go by.
You also have the option of buying Silkypix, Capture One, DXO, & other software once & riding it for a few years to get the most bang for the buck.
Basically, it boils down to what you feel most comfortable with. I personally like the Lightroom/Photoshop combo the most out of all paid software, but I'm not subscribed to them at the moment. Capture One is my next pick, but it is pricey at $299 or the $15 monthly fee for a year.
One thing is for sure. Like
Na Horuk said, it seems like "Cloud" computing is the wave of the future & a lot of software companies are heading that way. Things are going to get pricier when subscriptions are the only way to go.
Since I don't do photography for a living, I've decided to spend more time on open-source programs like RawTherapee on Windows & Linux & Darktable on Linux instead. I get some pretty incredible results out of RawTherapee, given that it's totally free. I'm currently trying to tweak Darktable as well, but their noise reduction features are kind of hard to tweak.
