If they already have a build system set up, it's probably exceedingly trivial to build .deb package for Debian and Ubuntu, if such a thing is even required. That said, the reason why they support Ubuntu is that it provides static targets. 12.04 will be supported until late 2017, which means that they users two years from now can install a .deb built today. Likewise, supporting 14.04 means .deb packages will work until late 2019. Especially for companies that want to develop on Linux, there's a huge benefit in first-party support from your vendor for the next four years.
