I'm not arguing against your position that the legal workings of a corporation, in the context of fair laws administered by a legitimate government, should not be splashed around.
But, if you believe we don't have a legitimate government specifically because some big corporations have bought the government, there really is no barrier between those corporations and the government they bought, and there is no difference leaking government or corporate documents.
Evidently, the people at Wikileaks think the latter.
I agree, in fact the lobbying system really bothers me. If that was all that Wikileaks published I might not have a big problem. But they didn't redact, they released everything, the majority of which just satisfies voyeurism.
Lobbying, if it is clean and transparent, and there is good access from expert organizations that are not just a fig leaf for buying the government, is fine and healthy. But, in contrast, secret influence-buying to enshrine bad copyright law into a hard-to-modify treaty, is not so good.
