Canonical contributed 548 changes in the period studied in today's report and would have cracked the top 30 if the foundation hadn't included "none" and "unknown" in the rankings. The maker of Ubuntu has been criticized for years for not contributing more to the kernel (and recently clashed with Intel over patches submitted to the company's graphics driver), but Zemlin [Linux Foundation Executive Director] isn't upset. "I am not at all mad at them. I think they do good work," he said. "You just kind of choose what's important to your org and where you can add the most value to the project and how it intersects with your business. They choose to focus a lot of their time and energy at higher levels of the software stack."
Canonical's contribution is more to the desktop and OS itself than to the kernel. The majority of desktop installations are either Ubuntu or Ubuntu-based, and Ubuntu is quickly becoming the server of choice as well.
Ubuntu is leading GNU/Linux adoption worldwide, which in itself is a huge contribution to the ecosystem, as it gets more programmers interested in various open source projects.

A quick Google search will produce this information. Furthermore, I think a survey of new server deployments would be even more in Ubuntu's favour, though gathering such information is no doubt difficult.
In the article it does mention that Ubuntu is the most popular distro for Amazon deployments...
Having been on the inside (EC2) and seen the numbers, I can confidently say that Ubuntu's AMIs are the most popular AMIs deployed on EC2. The stock AMIS take the top spots by an overwhelming majority, and most of the lower spots are filled with derivatives of the original Ubuntu AMIs.
Ubuntu's been working hard in the server/cloud space for a while, between the JeOS effort and subsequent, excellent tools for building customized installations around it. It's not just a brand or that makes them popular; with Ubuntu you get a sane system, style, and toolset for your system images.
Unless you are using unity, I don't see why a distribution should be called ubuntu based instead of debian based. A lot of "Ubuntu derivatives" are not based on unity.
Sure Ubuntu has a betteer installer and pretty themes, but the base is undeinably debian.
Because Ubuntu is more than Unity. I mean, by the "Unity or its not Ubuntu-based" standard you propose, Kubuntu (which is exactly Ubuntu -- sharing all the same repos -- with the KDE desktop and apps installed by default) wouldn't be an "Ubuntu-based distribution".
Heck, Ubuntu Server, since it doesn't have a default DE at all, wouldn't be an "Ubuntu-based distribution", either.
Ubuntu maintains a set of repositories for each version of Ubuntu, which (even when the same--by name--software is in Debian's official repositories, will often be different versions or otherwise different contents than Debian repos).
Kubuntu uses entirely software from the Ubuntu repos from the corresponding version number (e.g., Kubuntu 12.04 uses exactly the same set of repos as Ubuntu 12.04.) You can, in effect, switch from Kubuntu to Ubuntu, or vice versa, just using the apt package manager without changing the base repositories, just installing and removing the right packages from the ubuntu repos.
The difference between Kubuntu 12.04 and Ubuntu 12.04 is entirely in which packages, from the Ubuntu "precise" repositories are installed by default. The difference between either and any version of Debian is much greater.
The whole "unity or you have to call it 'Debian-based' instead of 'Ubuntu-based'" idea is nonsense.
Your choice of distro really just boils down to your package-manager preference.
Highly debatable. "Most accessible" installer perhaps, but as far as I am concerned, Debian's netinst has yet to be beat. Style isn't exactly high on my list of priorities during installation, it's not like that is something I do to show off in coffee-shops.
