HTTPie creator here. Just a clarification: HTTPie is still under the same management, and the CLI doesn’t have any telemetry. Little Snitch is probably warning you about requests to packages.httpie.io/latest.json [0]. That is done to let you know when a new version becomes available. It’s a static file hosted through GitHub pages [1] without any tracking. However, there’s currently a bug [2] that prevents the response from getting cached so that the request fires frequently for some users. It’s already fixed in a PR [3] and will be part of the upcoming release.
Good to know, however updates are a job for my package manager. Imagine dig or awk phoning home for updates? I could see a flag to ask for it specifically.
