I'm not enough of a power user to use a lot of the more advanced & unique features of photoshop, but a few years back I switched to Gimp & Inkscape for managing product photos & wire diagrams of things I need to laser cut. It's a bit more clunky and too a few weeks to learn the differences enough to get done what I needed to, but by now I have no need for any paid product much less one from a corporation that was a nightmare to deal with.
For anyone looking for an alternative I'd highly recommend checking out these alternatives. Especially with the devoted communities that provide a wide range of plugins it's possible to map a lot (not all) use cases onto these alternatives.
I'm not sure there are similar alternative to things like lightroom & after effects, and it may be that Adobe's ability to have a tight integration of the production pipeline through these produces can't easily be duplicated. But if your needs a little simpler, check these out.
