Text editing is one place I’ll absolutely never use nonfree software. In addition to the privacy concerns (my editor has the highest security requirements of any software I run), it’s also my most-used tool, and, as such, must always be able to be inspected and modified, as it is an extension of my muscle memory.
You might lock me into a cloud or an API, but my most critical tools that take up the deep parts of my habits will remain under my control.
