Maybe then can switch to British/European tools. I switched from PS to Affinity Photo, which was much cheaper, a perpetual license and covered everything I needed.
Obviously, a heavyweight user will probably still need add-ins or tools that only Adobe provides, but there are professional alternatives out there - I switched from Lightroom + PhotoShop to CaptureOne and Affinity Photo and I am very happy with it.
The other question is, should we be teaching students to use a tool or teaching them how something works? When I was at college, we used 2 or 3 different tools, E.g. DisplayWrite, MultiWrite and WordPerfect and we could use whatever tool we wanted privately to create course work (I used Arnor Protext). We were taught how to word process, not how to use WordPerfect, for example.
I think giving students a range of tools and teaching them how different features work, as opposed to parrot-fashion which key presses or mouse clicks are needed, is much more important.
