What needs to be emphasized is that hardware wallets are not imune on clipboard malware attacks
No wallet will be immune to clipboard malware attacks. Even an air gapped wallet won't be immune, since you are generating the transaction on a live machine before transferring it your air gapped machine for signing, so if your live machine is infected then you are still at risk. The point of the hardware wallet is it forces the users to make a second confirmation of the address after hitting "send" in their wallet. If the user chooses to skip that and just confirm it without checking, then no amount of hardware or software engineering can prevent that.
but because they do stupid things (entering seed on fake sites, reseting device without seed backup, sharing seed with friends...)
You are absolutely right, but if our metric for whether a device or system is secure is whether the user does something stupid with it, then every security system in the world is at risk.
