It seems to be that it comes as a complete surprise to the community how Canonical developed their NIH syndrome.
It happened because the "community" is completely impossible to work with in the vast majority of cases. Their work is intermittent and often of low quality, which doesn't necessarily apply to Wayland but Wayland is taking unreasonably long to come out.
Canonical is a company that cannot afford what they did from 2010-2012. They have duplicated so incredibly much work now. Unity has been written twice, soon thrice, for instance - and they only did so because the GNOME Foundation had no clue what they were doing, and tailspun to copy as much of Unity after Canonical stopped contributing as they could. The Red Hat company said that it was impossible to earn money off of Fedora because it was basically substandard.
Canonical also constantly gets complaints because of community work - and I suspect it's only a matter of time until they decide to remove Nautilus and GTK+, and obviously X.org is something we all want killed. They've already decided to remove the inconsistent tray icons. The new mouse settings panel is something I complained about because they rip out important features for gamers. Yes I'm ripping quite a lot on GNOME here but it's not just them; they just happened to have made the majority of the software that we found inside Ubuntu. Even Debian, their packaging format, has been forked by Canonical - and that is a very long time ago.
Right now Canonical has the chance of a lifetime. They have gamers and serious companies knocking on the door asking for an alternative to the restricted webpage that is the future of Windows. Canonical can offer this, but they can't rely on intermittent work and changing goals that don't align with their own. They could have contacted Wayland, but to be honest I think they're fed up with the whole thing, and they're scared of Wayland suddenly changing in a completely new direction that they heavily disagree with, such as what happened with GNOME.
Now you know why they have NIH syndrome. They've had their own efforts duplicated far too many times, especially by GNOME, to care any more. They still want to provide a free software operating system (onto which you can install proprietary software if you so desire) but they don't want to do it with you. Specifically you. That's why they don't talk to you. They have their own development community now - some of which they've hired, and that's it.
