Research papers in creative cloud? I am guessing she is using something like InDesign or illustrator to make pdfs or maybe Acrobat? I think you need to clarify what her workflow entails to get better answers.
But going with my assumptions, it sounds like she can get away with using some kind of Office suit instead, maybe 365? not that it would solve the enshitification of apps problem… But I do consider it a stable program both as installed apps and on the web. There are also endless tutorials and support to get if she is running into issues.
With that said, it is probably not worth it if she is a boomer. It would take a long time to get into a new workflow and it would affect her output. If she is used to adobe she should probably stick to it.
Would you mind posting a link? ☺️
