Hi Dave,
Welcome to PPRuNe.
The page you linked is interesting but it seems to leave a lot out.
In spite of its remarkable success in pursuing its mission of public outreach and education over the past 14 years, VWC has made less progress towards financial viability. As a result, it has continued to rely heavily on its primary donor for operational funds and has forecast continued significant deficits for the foreseeable future. In the fall of 2016, the independent board of VWC therefore determined that it would be prudent and responsible to wind down the existing charitable organization and announced plans to do so at the annual meeting of VWC members held in December.

Can you expand on this somewhat terse statement?
