Haters will always hate. Keep up the good work guys! People seem to think they are entitled to something when using open-source software, but they're not. It's still the people working and maintaining it who get to take the decisions, and if you guys think you need analytics to provide a better tool, go for it.
I also completely understand the need for default opt-in. I probably wouldn't check the prompt and leave the default, but for a project like this, I honestly don't mind sending usage data.
If you're not happy with the direction taken by the maintainers, find another tool.
