I think you actually believe this. Search around and find the history behind Atom's telemetry, and the absolutely *entitled* attitude the developers had about it. It took a lawyer to convince Github they could not make the telemetry mandatory.
"seldom" does not mean "never".
I was unfamiliar with either Atom or the history of its telemetry. (I use Sublime.)
I did some quick searches.
There was a robust discussion of it in GitHub Issues for the project.
https://github.com/atom/atom/issues/4966
(And others).
Seems to me open source worked the way open source is supposed to work. Public distribution of the source, open discussion. Issues of concern are exposed through publication and discussion. One is free to use the product or not, or to modify it to suit one's own needs, or to create a splinter project that addresses areas of concern.
(Depending, of course, on the license. I do realize that open source doesn't always come with the right to redistribute modified copies.)
Anyway, I suggested one solution that is an alternative for OP. OP can go read the source code for that solution (if so inclined and able) and can read Github issues looking for concerns, and search for additional discussion.
With commercial closed-source software, that vetting is not possible. There is no publication of the source code. There is (usually) no public discussion of the source code or of decisions made around it's creation.
