As mannycalavera mentioned, Linux users are "contrarian"; yes we tend to repudiate what is the mainstream, and in the Linux world that is Ubuntu. Ironically, Ubuntu did more for making Linux mainstream than anybody else.
Ubuntu have amazing technologies but it is usually unable to compete with the competitors that has the no only far more capacity for new development (usually faster, not necessarily more innovative) but also to push it harder into the market.

One thing most people ignore, even among Linux users, is how small Canonical actually is :

Canonical employees 500 to 800. Red Hat close to 20,000 (and, in top of that, it leverages IBM’s global engine!).
Canonical makes some $200 million. Red Hat makes $5,300 million.
Even, SUSE (OpenSUSE) is far larger than Canonical.
Proportionally, Canonical makes far more contributions to the community than the other 2 companies.

Canonical, if you are listening, here is my recommendation to you:

You can both cater to large corporation as a competent and resourceful partner, and also to Linux enthusiast as the cool, approachable, and welcoming collaborator you are. Search for that formula.
Get out of London/ Isle of Man. Make a bold move to a new hub that can expand your horizons... Barcelona, Gibraltar or even a bolder move; Mexico, Indonesia,... the UK is dragging you down in costs, image and even talent.
