At least with LastPass you know they have a commercial model and reputation to incentivise better behaviour. If you download something that is free then that pressure doesn't exist.
have you read their privacy policy? They layout they can spy on everything and share with anyone they want.
You'd think if they were serious about privacy their privacy policy would just say "we spy on nothing and collect nothing and share with no one". 1password effectively has that privacy policy, lastpass does not.
