But until then, you can look at the wonderful direct blog action by Lars Wirzenius – In defense of Nicole and others after this shocking episode. I hope Lars is wrong in this case and the Davids will join together in their common interest to overthrow the Goliath.
There is a far longer prelude than Lars describes, going back to the April 2005 launch of Liblime (announcement here). An independently-authored history of Koha and LibLime and the recent problems can be found at LWN.net (US$7/month if you woud like to subscribe and support LWN).
Actually, I’m not sure if PTFS is even a Goliath. They seem to stomp around a lot, but how big are they? Biggest credible guess I’ve seen is 125 people across all products (not only Koha), which is fewer than the 150ish Koha-Community developers (not all supporters). So there you have it: Koha is bigger than PTFS. Literally.
