The post looks a bit weird on first sight: "I always knew LastPass has a ton of flaws, but promoted it anyway".

This may make sense though. LastPass seemed to be the only one with a good enough UX. And without a good enough UX, you can't make users actually use it. Using an imperfect but usable password manager is still much better than not using one with better security but poor UX.

(Here comes the old adage: make the friction low for the customer, and any shortcomings elsewhere will matter little.)
