Netdata system monitor embeds spyware

The netdata installer says the following:

The following changes will be made to your system:

  # USERS / GROUPS
  User 'netdata' and group 'netdata' will be added, if not present.

  # LOGROTATE
  This file will be installed if logrotate is present.

   - /etc/logrotate.d/netdata

  # SYSTEM INIT
  This file will be installed if this system runs with systemd:

   - /lib/systemd/system/netdata.service

   or, for older Centos, Debian/Ubuntu or OpenRC Gentoo:

   - /etc/init.d/netdata         will be created


  This package can also update a netdata installation that has been
  created with another version of it.

  Your netdata configuration will be retained.
  After installation, netdata will be (re-)started.

  netdata re-distributes a lot of open source software components.

Please type y to accept, n otherwise:

However, it does not tell me that it's going to silently spy on me. I don't consent to analytics. It spied on me and sent my data away without my consent. I had to uninstall it, clean my system, and reinstall it using an obscure, barely-documented flag.

This is not respecting user consent. Notify the user before spying on them, if you intend to do so, so they have an opportunity to cancel and delete your software if they don't wish for that to happen.
