Eh. It's not like we'd be getting anywhere at sub-light speeds regardless and a working Alcubierre drive isn't exactly right around the corner.
On the other hand, it might make it harder for anybody with working FTL to get to us, which is probably a good thing. If they saw how we're conducting ourselves at the moment, orbital bombardment would be the best we could hope for.
It's like reading an article about a petrol refining company, who, having prior experience with gasoline as a useful and profitable substance, decides to seek venture capital for the development of a petrol-based fire-extinguisher. They obtain the funding - presumably because some people with money just wants to see the world burn and / or because being rich and having brains is not necessarily strongly correlated - but after having developed the product, tests conclusively prove the project's early detractors right: The result is surprisingly always more fire, not less. And they "don't know how to fix it, while still adhering to the vision of a petrol-based fire-extinguisher".
