No. That's ridiculous. Whatever the rules say, there's never a situation where it's morally OK to change someone else's words and leave them attributed to them. Imagine I had edit rights here on HN, and I could change your message to:

> I think goats are sexy.

> - jodrellblank

Even if the site allowed it, or even encouraged it in certain small circles, you would not be OK with this. Or if you would, surely you could appreciate that other people absolutely would not be.

Sometimes people edited my SO answers in ways that were factually incorrect. A colleague or would-be employer might see that wrong answer attributed to me and suspect that I'm incompetent. That is not acceptable. Again, it doesn't matter if the license permits it. Morals and ethics do not.

This is different from, say, forking my software project and releasing an altered version. People would prominently see that you're publishing the changed version under your own name. That's fine. You having the ability to go in and change my own published code, without my permission, so that people see my name on your work, is morally and ethically wrong (and a major security risk). No rule or guideline on SO can override that principle.
