It is all but certain that Ars Digita Corporations, one of the bright lights of open source software development, will be releasing their new version of their Community System (ACS) as proprietary. Rumours to this effect had been floating around for a couple of months, and a recent article in digitalMass confirmed them. New ArsDigita CEO Dan Keshian is quoted as saying that while the ArsDigita products that have already been released will remain freely available as open source, "the future is currently open for discussion." A call today to Keshian confirmed that the new ACS collaboration modules are becoming a commercial product that will focus on what he calls "enterprise collaboration management."
