Choosing to fail means you shouldn't begin the project in the first place.

Correspondingly, if you are beginning the project, you should not make choices that will result in failure.

I don't think i'm "choosing to fail," I'm choosing to accept the outcome given an effort to prevent it. Sometimes you try and it doesn't work out; I'm not committing the mortgage to the site or the effort, and I'd like it to pan out because I think its progenitor had a raison d'etre, and I was part of it when it was good and I think there's room for it now.

And if the moment's gone, well... that's the way it goes. That's not the same as "choosing to fail."
