I’ve been involved with open source software (mainly Drupal) for the last 10+ years. There has been unquestionable growth when it comes to Drupal adoption. I’ll spare you the war stories, but the decision paradigm has shifted from executives asking, “why should we consider Drupal?” to “why would we want to look at a proprietary, licensed based option and pay seven-figures in just licensing fees alone for ‘closed-code’?”
