Note that Vintage Computer Festivals refers to a specific festival held by the Vintage Computer Foundation (VCF). Jason isn't saying he will never go to any festival ever again.
VCF = Vintage Computer Federation, a national non-profit
VCF also = Vintage Computer Festival
VCFestival East and West are run by VCFederation. VCFestival MidWest is not.
Vintage Computer Festival as a name has a complicated history, but the short version is anyone can use the term and does use the term.
VCFederation also manages the warehouse and museum space in Wall, NJ. The blog author has an issue with VCFederation, not all VCFestivals.
