I can see it going either way.
If they hate it, I'm sure they'll try to block the script somehow. Either by changing stuff on the page or by threatening legal action.
If they love it (they might see it as a way to re-gain the trust of their user...), they might integrate it into their page.
Either way, as I said previously, I'm glad it's out in the open, that will prevent them from disappearing the project.
