Presumably preference of their users. From what I know, other than for cursor, the GUI interfaces are less popular than the TUI ones. Personally I also did not expect that I would really like the TUI experience, but it's hard for me to switch away from it now because it has become so central to my workflow.

It's easier to ship a TUI app cross-platform, the constraints around UI and state are often simpler, and some good libraries/frameworks (e.g. [1][2]) exist to make a modern-looking UX.
