Although Adobe has been dominating some markets for a long time, they always had, and they always will have competitors. They never were or never behaved like a monopolist. Well maybe in print media and graphic design for one or two decades (but not before an not anymore), and in video now and then (when Apple made some bad or at least strange moves). For the rest (web and app design and development, 3D, audio, music, etc.) They always have been sharing the playfield with many others, or have been just vaguely present in certain areas.
