This site has never been hosted at Infopop.  It used to be hosted by Interactive Ideas . . . maybe that's the source of the confusion.
This "change to another BB" thing has come up before, sometimes even be me, but I just couldn't find a real compelling "killer-app" kind of reason to do it.  I also agree that commercial doesn't automatically mean evil.  Remember, not every company is like Microsoft.  Technically, *I'm* a company (well, a sole proprietorship), and I really wouldn't like to think that *I'M* evil just because of that.
I have seen other forums convert -- 
AppleInsider moved from UBB to vBulletin, for example -- so I'm sure it can be done.  But I have a hard time believing everything will convert smoothly.  Conversions have a funny tendency of screwing up one way or another.
