Guys, what is your problem? The only way these guys have ANYTHING is if you use your master password on an actual website other than just logging into your lastpass account.
Now, if your master paswoord is boobies, then, you're in trouble. But if you use anything remotely decent, you are fine.
Especially if you use 2 factor authentication any time you login outside your known trusted devices the diminishing returns are so low...
And unlike most companies, at least LastPass has the integrity to actually tell us when there has been a problem. You know, because that's something that responsible companies SHOULD DO. But mostly, they DON'T.
