Cheney energy task force: Why didn’t an enviro group just spill the beans?

OK, we now officially know who sat in on Vice President Cheney’s energy task force in spring 2001. It had everybody from the American Petroleum Institute to Defenders of Wildlife.

Here's what I don't get.

There were representatives from legitimate enviro groups that sat in on task force meetings.

I know the meetings were on different dates, but did Cheney never mention a thing about energy companies during meetings with environmental groups? Why didn't somebody just spill the beans and leak this? Even a minor leak?

What, the vice president who’s addicted to secrecy is going to sue you over leaking information, leading to even more of it coming out in court?

Or, if Cheney remained absolutely close-mouthed, why did environmental groups decide to participate in the process at all?

Frankly, it does raise the cynicism hackles a bit, making me wonder if some groups like to keep the confrontational pot boiling because it makes for better fundraising. By participating in the process, they got some talking points; by harping on the secrecy theme without doing something different about it, they got much bigger talking points.
