The emptor's counterpart, the venditor, also has a responsibility. I wouldn't dream of offering a free product that handles one of the most important aspects of consumer data security and then drastically altering it with only four weeks' notice. Many were introduced to LastPass, probably reluctantly, by more security-literate friends and family. These are the folks most likely to be squeezed in this very short transition period because they won't necessarily know how to navigate to a different product and would probably be more likely to do something risky in response.
