Using a GUI doesn’t mean there is no code. SAS JMP lets you work on your data visually yet you still have code that defines you tables and plots, and you can easily work with git or hg.
JMP was precisely my counterargument to this whole piece. JMP is an excellent data science tool when used correctly and allows for reproducibility. You can even call R from JMP if you need to do something that is easier in R.
Further, as others have commented, exploratory data analysis is much easier in an environment like JMP than it is in R - when you're just playing around with the data and trying to get a sense of it, it's much easier to make quick approximate graphs in a GUI than in a command line.
