>What’s wrong with paying for a product or a service if it’s better for my students? Isn’t the teacher’s job to find the best available tools for their students

There is nothing wrong with paying for something, but what's better is relative.

Isn't it better to not give away students' private information? Isn't it also better for CS students to be able to look at the source code of tools they are using? Inevitably you will need to choose some metric with which you'll measure quality of a software, that metric is subjective. This guy chose one which valued aforementioned qualities more, if you teach your own class you are free to choose software which better fulfills your subjective criteria.

I pay for SublimeText because I genuinely feel like paying for it - think about it - why does someone go out of their way to spend money on something they wouldn’t feel is “better”? I agree that criteria of what’s better is subjective but regardless, I don’t think it’s saying anything my stance on open source software.
