I may be able to speak on this since it is mostly my sole purpose here at iX to do stuff within the community.
The mission has not changed and unless I am out of the loop is not changing. We simply want to make it a great place to be for the community as a whole with enhanced search features and better features for our awesome mod/admin team to help them be more efficient. Another thing is that Xenforo, while on the surface might be great, on the backend was struggling to scale (pun intended) with us.
At the end of the day, we all share the same mission, believe it or not, that is to help make TrueNAS a better product for the end user. We could not do it without the community.
