Con Latest versions of Photoshop are subscription-only
While you can still buy CS6 from 2012 without needing a subscription by contacting Adobe support or the cut-down Photoshop Elements, any full-version version of Photoshop past CS6 requires a subscription.
Con Learning it can take some time
While you can relatively quickly learn how to perform a few basic image editing tasks, understanding Photoshop's ins and outs can be difficult. It's partially due to the sheer amount of functionality that Photoshop packs (and understanding that some of the advanced functionality can take a while to understand on its own), and partially due to it being aimed at professionals with little hand-holding for novice users.
Con Batch editing of images is not straightforward
Photoshop is designed to work extensively on one image at a time and while batch editing support exists, it's not that intuitive to use.
Con Affinity Photo is just as good at a fraciton of the price
Switching from Photoshop to Affinity Photo and it's hard to notice the difference quality of a professional's work. They say that PS is the industry standard, but so very few pros that tried Affinity Photo ever look back.
Con Asset management capabilities are lacking
In Photoshop asset management is done through a separate program called Bridge. As Bridge is supposed to be a file management tool for not just Photoshop's files, but for files generated by all of Adobe's applications it covers a breadth of capabilities, but not depth.
Con Very slow startup on some systems
Depending on factors like how many fonts you have installed, Inkscape can take upwards of 30 seconds to launch.
Con Uses its own SVG-format by default
Inkscape might use SVG as its default format, however this SVG's contains some additional SodiPodi/Inkscape additions that can be troublesome if you want to import the SVG into some other application.
Con Based on the GTK widget toolkit
Software is based on GTK, so it might not integrate well in non-GTK environments. It also requires many dependencies on those non-GTK desktops. It also adds dependencies to GTK-environments since it is written in C++ which requires the gtkmm wrapper/interface
Con Mac version is in worse shape than Windows/Linux version
Con Incompatible with previous versions
Sometimes backward compatibility breaks. For example, pre 0.92 SVGs are incompatible with later releases (due different default resolutions).
Con Limited work with ICC CMYK color scheme
Support for ICC color profiles only in SVG files.
Con No support for large printing machine system
No support for large printing machine environment, except exporting the resulting artwork to PDF.
Con Y-axis inverted
0,0 coordinates begin in lower left corner, not upper left corner as SVG standards define.
