If these tools are so wonderful, why don’t they offer command-line versions?
I’ll tell you why: because it would likely mean they would sell fewer copies.
Unless they put in a whole bunch of additional restrictions in the EULA, such as
* You can’t run the program via SSH or a PTY, because this would allow
multiple machines to make use of a single copy, which is not allowed.
* Shell scripts are allowed, but any loop invoking the cheaper version of the
tool is only allowed a maximum of 100 iterations. Also you must write the
scripts using csh, not bash.
* Pipes are limited to a maximum transfer of one gigabyte per day.
A CLI gives the user power over the computer. While a GUI is a great way to
give the computer, and proprietary software companies, power over the user.
