I've been hearing so many stories related to how people lost money even though they use a HW, claiming they never store their seed phrase online, and so on.
Take note that there is no method of security that is 100% foolproof, some people think that once they buy a hardware wallet they are 100% secure, but there are other things that's expected of you even if you have a hardware wallet. Some of the people you talk about may have exposed their seed phrase backup or they downloaded a fake wallet software. A hardware wallet truly provides better security than an online software wallet, but the users still have to ensure they have very good opsec and that they buy a recommended hardware wallet from the manufacturers, and not from any other source.
