Photoshop + Lightroom cost 12 euros. The CS price you mention is for all the apps in the creative cloud, not just the raster image editing bit, so that's unfair to compare $50/month to "alternative to krita or gimp". 12 euros per month is just 2 euros more than many of us here pay for lots of entertainment, such as music streaming services. It's well worth every penny spent just to not have to deal with the horror that's GIMP's UI. It's a lot cheaper to get access to Photoshop than it used to be before the monthly licensing scheme.
