You sound like the quintessential, disgruntled former employee (or worse).
When I look at a lot of the actions of Greenpeace, I see positive things being done including being involved in educating the public on the pollution mentioned in this boingboing post. I’m happy to say I’ve donated to them and I will continue to do so.
I hope you’ve found more fulfilling employment elsewhere in the meantime. And, if you see areas of improvement for how Greenpeace works and you really want something done about it, I would suggest you start by providing valid links/sources, etc. to begin with.
