I'm not sure how I feel about programs phoning home like that. I tolerate it with apps, but command line tools ought to be doing their stated function when run.
By contrast, git is a tool that I manually invoke on the command line, and when the process terminates it's done. Having that phone home at runtime feels more invasive.
It seems like people are worried about privacy without thinking it through.
Maybe even a push update you can subscribe to.
