This seems to me to be unobjectionable, because the BSD license in fact does give people the ability to close their product code, and place such restrictions on it, and that seemed to be part of the idea behind the BSD license in the first place.

And, remember, as > Bruce said, it is marketing. this _is_ objectionable. To begin with, the glib remark that it's "marketing" suggests that tossing mud at others is ok, as long as it's all in the spirit of selling stuff. Second, and somewhat more importantly, I think, the claim is an apples-to-oranges comparison that the community is _not allowed_ to rebut, because EnterpriseDB isn't willing to let us. It's reasonable to expect such behaviour from other database companies, but it seems a little like eating your young in this case. Note that I actually wouldn't have any complaint about the "200% faster" claim if the claim simply said _why_: "EnterpriseDB's sophisticated Dynatune tool automatically provides performance gains of up to 200% over untuned PostgreSQL," (or something similar) wouldn't cause me to bat an eye. Quite apart from issues in the community, though, I wonder whether this angle isn't subtly undermining EnterpriseDB's own arguments. If PostgreSQL is so great, how come people are able to get 200% increases in performance out of mostly the same code without much work? Why isn't the super-excellent PostgreSQL code already doing that? Oh, and some of these things are new features? Ah, so it's _not_ just PostgreSQL, tested by the community &c. &c.? I don't think you can make the argument work in EnterprisDB's favour on both sides. I am very far from being someone who objects to closed bits of code, to people doing what they want, &c. I pushed hard at Afilias to get Slony (and some other code) released under the BSD license partly because I think it's good for the community, even if part of the community goes away and makes changes in secret (before or without sharing those changes over the long term). But I don't think it's cricket to be slyly suggesting that the basic code is so much worse that the magic of EnterpriseDB's contribution solves everything, and then tell the community they can't test it themselves and publish the results. It might be permitted by the license, but it isn't part of any community behaviour I can think well of.
