No? You'd have to carry out the third-party software RCE on each individual user to install a keylogger. This attack installed a keylogger on a single computer, then exfiltrated millions of passwords. Centralization is a bad thing. Same modus operandi maybe, but nowhere near the same impact.

I think the point is that all of the users of Lastpass whose passwords were put at risk through this one breach. Using Lastpass means that a single, high-value target is now an attack vector that can affect you. If you keep it offline yourself, you're not likely to be a high value target, and you won't have to worry about the 3rd party with your passwords being compromised.
