For additional reasons to avoid Ubuntu or Ubuntu-derived distributions, expand this section.
Ubuntu's limited contributions to the upstream Libre projects they heavily rely upon is a policy decision, not a coincidence. Canonical founder Mark Shuttleworth has stated: "It is absolutely true we have no interest in the core fundamentals of the Linux kernel, none whatsoever." [

Canonical only makes major contributions when forking significant projects; for example, Wayland into Mir, GNOME into Unity [
https://web.archive.org/web/20150912223445/https://ask.fedoraproject.org/en/question/25127/how-to-build-unity-in-fedora/
], and .deb packages incompatible with Debian due to zstd compression. [

] This appears to be a consistent attempt to fragment the software stack, lock in users, and apply pressure on competing distributions and vendors. [

The Ubuntu Contributor License Agreement gives Canonical complete power over patents that cover contributed code. Essentially, they are granted the right to re-license this code under any license of their choice, including a proprietary one.
Ubuntu also has a history of treating staff in a hostile manner. For example, the Kubuntu spin project lead was unilaterally removed without warning and against the wishes of his team members. [

] Canonical also diverted donation funds originally intended for desktop spin projects (Kubuntu, Lubuntu, and others). In Kubuntu's case, after funding was abruptly cut, Blue Systems had to step in to save the project. [

Canonical has also enforced an unreasonable intellectual property (IP) policy over packages in its repositories for years. This included claims that Canonical owned the copyright of any binaries compiled by their servers. After the FSF intervened and arranged a resolution over two years, the policy was amended to state that Canonical’s IP policy cannot override packages with GPL licenses. However, this means any package with a permissive license is now copyrighted by Canonical. [

Unfortunately, downstream forks based on Ubuntu cannot be relied upon either. For example, the popular Linux Mint distribution was threatened with loss of access to Ubuntu infrastructure unless they accepted Canonical's binary licensing terms. [
https://forums.linuxmint.com/viewtopic.php?t=152450
] Since then, Linux Mint has developed a Debian-based version instead. Canonical's vague trademark and IP policy has become toxic for downstream distributions. Many have wisely chosen to re-base on Debian instead of Ubuntu, including Kali, {{project_name_short}} [ [[Dev/Operating_System#Switch_from_Ubuntu_to_Debian]]
], and others. [

A final major concern is Canonical's cooperative relationship with Microsoft. This should raise red flags for Linux users, given Microsoft's historic strategy of "Embrace, Extend, Extinguish" in regard to Free Software. [

In a fashion similar to Windows platforms, Apple operating systems also pose many security and privacy threats.
