The problem is the kind of work that Adobe's tools are used for. Designers, video editors, artists, illustrators, etc. These are all careers that people get into by having a strong portfolio of prior work, which usually requires them to make stuff outside of professional work. So they need tools for personal use to get hired. Then when they start working they are going to want to use the tools they are familiar with.

That absolutely has the result of eating into Adobe's bottom line. Even big companies that can easily afford Adobe's prices aren't going to pay them if their employees don't even want to use the software.
