Simon delivered a talk for the new Tidelift conference “Upstream”. In it he drew together the threads of several earlier posts about the rights ratchet model (“bait & switch meets boiling frogs”) using the history of the now-defunct Sugar CRM open source project as an initial case study and then examining the various ratchets that remove rights from open source project participants, ways to detect that a project is actually a rights ratchet and steps to mitigate the consequences including promoting permission in advance.
