The notion that people choose to use computer applications because they are useful at accomplishing tasks is extremely outdated. The vast majority of software use is not voluntary.
We choose or are required to engage with a person, organization, business, government. They dictate what software to use for the interaction based on what is most convenient and advantageous to them.
I have been thinking about this ever since years ago Julie explained to me that the reason she dislikes graphical user interfaces is they feel like prisons because to a much larger extent they are an experience fully orchestrated by somebody else.
@chris__martin That's mostly because most systems fail at doing GUI right.

BeOS' BMessages enable full automation and scripting of GUIs, if one wants to.

As for dictated software, that is why one acquires a non-Free/untrusted device with the mandated malware, and other more trusted devices that one does not install such malware on.
