I expect my terminal to be a much more secure environment than my web browser. When an application starts communicating with the internet, I have no choice but to treat it with the same level of scrutiny as my browser.
Even making telemetry opt-in means that it has the capability to send information to the internet that I don’t know about, which means that I have to treat it like an application that can do that.
Honestly, this freaks me out. It’s an angle I’ve never considered before. Now I need to make sure my current terminal emulator (kitty) isn’t sending information to the internet without my permission.
