* Netdata dashboard is now closed-source, proprietary software, and there is no alternative tool to exploit data returned by the netdata agent.
* The Netdata dashboard now imposes an arbitrary limit to the number of monitored nodes unless on a paid, monthly subscription plan.
* Upgrading from Netdata's previous, Free and Open-source releases silently leads to installing proprietary (since v1.41) and artifically limited (since v2.2) software.
* The new limitations and license were not mentioned in the release notes
* Netdata has been removed from Debian repositories.
* Free and Open-Source versions of Netdata, and versions without this limitation, have been removed from Netdata's APT repositories
* Netdata has repeatedly added dependencies or interactions with third-party cloud services in the dashboard (telemetry, features required a Netdata cloud subscription, ...) and misrepresenting itself as Free and Open-source software
