A disappointing move with no benefit to the community and only one benefit to the new owner - thousands of backlinks pointing at his domain. That's why he bought the project.
Saying that moving PunBB to a new domain is:
a way for our benefactors to promote their other services to the PunBB community and to promote PunBB to users of their other services.
is either naive or disingenuous. Promotion either way could have been achieved just as easily without moving the domain. When people start lying / treating a community as stupid, it never ends well. Note - I'm not accusing any one in particular, but something smells bad.
Taking a quick dig in to Victor Sazhin's portfolio, it shows that he owns a very large network of questionable quality properties. PunBB has therefore transferred ownership from an open, passionate, community-focused project manager to a shady, non-communicative individual who is evidently motivated by money first and foremost. IMHO of course.
Also, note that the community at feed.informer are less than happy with the new owner.

. There is a *default* style - it's the one we all see immediately after install. The few PunBB installs I've done required nothing more than changing some colours and maybe adding a logo to the default design ... because the default design is 'just right' IMO. I'll bet that applies to most installs.
