The emphasis here is "I dont think" so this is a personal assumption not a fact based theory.
So I would not talk about evidence but indications , I have been an active participant of the pharo community for 4 years now. There are not many messages that I have missed in Pharo-dev or Pharo-users or even the IRC and Slack channels. Though lately it has become harder to keep, which yes its a an awesome thing ;)
Nonetheless I remember a couple of times people asking info�� for undocumented projects. But not more.
