It may be satisfying to, as you suggest, "burn" the company; but it's also unprofessional. Granted, the startup that rescinded the job offer was behaving unprofessionally, and may even be civilly liable for it's actions, but that does does not mean that you should respond in kind.

Huh? Why would he want to subject anyone else to the same thing he was subjected to? By not naming them, he just screws over the next guy.

A rescinded job offer is a big deal, particularly given the guy's immigration status. I assume this was discussed and that he'd need to transfer his H1B. The company by then would've known he had handed in his notice and any HR person should know this potentially triggers immigration issues.

Name them and shame them I say.

Like you say, this may indicate the company is in trouble financially so any existing employees and potential applicants should be aware of this.

"Naming them and shaming them" is not unprofessional. If you act in an unprofessional way towards me, why is it 'unprofessional' of me to tell the world about it?

Granted, it would definitely be unprofessional to post a large rant filled with swear words and name-calling to your blog, but approaching journalists that might want to pick up the story, or just posting the facts to your blog (and possibly posting that to sites like reddit, digg, hn, etc) is not the same thing.
