They don't tell me anything, and make it sound super urgent, then redirect to a "subscribe here to reveal the alert" page.
I really expect better from an established player in the infosec space like Lastpass. That's just retail FUD stuff.
Show me the alert, and if I find it valuable, I'll subscribe for future alerts. If it's not, I'm going to be super irritated that you used fearmongering to scrounge a subscription out of me that now I have to be bothered to cancel.
