Sorry, you're wrong, for many years that iphone is not the leader in the mobile market, android thanks to the diversity of distributors. Linux does not have the largest share in the desktop computer market, but adobe does not target these types of users either (unless they do not know of commercial strategy). Linux has a good part of the users of application developers, to others, most of those who use Linux for development also use Windows. To say that Linux does not have the highest quota in the market is an error of ignorance. There are many users who also use Linux if they are willing to pay for an Adobe solution, in addition to its normal use in other operating systems. For example, many Windows users would transfer their use to Linux if Adobe supported it. Gimp is not a good substitute for photoshop, but krita if thanks to the use of vectorization of layers, predefined styles and various tools, but still photoshop is more advanced and unfortunately, like microsoft has created a dependence on the market over the use of the psd format instead of having created a contribution to the community by creating free file formats compatible with other software, preventing the monopoly of software and operating systems duopoly. Clearly Adobe is a company that cares more what it manages to sell to strive to understand the needs of people or their users as if they do the largest companies like Google, Amazon and Virgin.
