"Movie stars are people. Corporations, such as Apple, are not people. They are businesses, at all times. Business practices and information are always in the public interest. Trade secret laws have been dubious from the get go. When information gets out from a company (whether in violation of an NDA or not) that information is almost always in the public interest."
So which is it? Is Business information always, or just almost always in the public interest? I'm going to guess that you realized your first claim was absurd, and tried to correct it by adding "almost".
Here's a hypothetical (which nicely refutes your first claim, and makes pointless your second):
Company A is researching a product which will bring joy and happyness to millions, cures athletes foot, and will do your taxes. Intrepid blogger B induces one of company A's employees to break his NDA, and publishes details about the research. Company C who makes tax software and anti-fungal powder, reads said leak, and quickly buys and kills company A before their product can be completed.
In that (very hypothetical) case, public release of private business information has worked against the public interest, and the unhappy public must continue with itchy feet and sub-standard tax software.
More importantly, one could make the same case for the public viewing of personal information that you've made for business information. It is certainly in the public's interest to have it be widely known that your are a hopeless alcholic, and constantly default on loans. But I'm sure you wouldn't agree that private, personal information should be publicly available. Why so for people and not for corporations, who are, at their basic level, a group of people?
