The video you posted 100% proves my point. Nothing in the video is security related, Its all privacy points. Getting attacked by scammers, phishing emails, phone calls etc are privacy threats, because you provided your main email, phone number etc where you should not/did not have to. I am saying again privacy is orders of magnitude bigger thread to a common person than an attacker spending resouces and targeting a random person. Please recognize that privacy and security are different things, people obsess with security when its a smaller threat to them.

Non of the threats in the video would happen if people didnt share their lives, emails, phone numbers etc all online in plain sight. Non of the threats required an attacker to use a vulnerability to enter into pc/phone/network etc.

Privacy - use email aliases for different websites, different phone numbers for 2FA, do not use social media or at least do not post all your life , real identity, email and a phone number on there etc

Security - dont use no longer supported software, use an offline password manager, you still have no chance against 0 day vulnerabilities

/for a good measure, i copied the link you posted and entered into piped.video, example of privacy.
