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.
