However, I have to disagree on the "true free software". At least at the time I investigated, there was no procedure for upgrades across major versions apart from "hire us", and the website was quite bluntly announcing that bug reports were very likely to be ignored unless they included the identification of a customer support contract, and patches would be similarly laughed at.
Did that change in the last two years?
(If anyone cares: I switched to Tryton, which happens to be an OpenERP fork.)
