Setting aside the question if on by default telemetry is unethical in general, I personally think it is, my point in this comment is that in the context of open source it is impossible for it to be because: The whole point of open source is the security of the rights and freedoms of the users, and in case of a conflict with the convenience of the developers, the user rights take priority EVERY TIME. If you're not ok with this, you should not write open source software. If nobody opts in to your telemetry scheme if it were the default to choose, too bad, you're just gonna have to live with it and respect user choice no matter how inconvenient or how much better the alternative would be for everyone. If you fail to grasp this very basic thing you will be better served working on proprietary products instead. OSS is not a product you own, it's a shared resource you are in charge of stewarding and the ethical burden is much higher because of that. I checked, Go uses a permissive license, Google is more than welcome to run a proprietary fork with telemetry built in. Keep that out of open source.
