We wanted more security in order to keep Bitcoin safe from hacks, scam, and also fraud but the more we find solutions, the more we are drawn out from being a decentralized community.
I've never once been a victim of a scam, hack, or fraud. Why? Because I don't click on random links or download random files, don't send out my KYC documents and personal information left, right, and center, don't believe in shitcoins/ICOs/doublers/Ponzis/HYIPs/etc. which promise ridiculous returns, and so on. This facial recognition nonsense is a completely over-engineered solution to what is a very simple problem to solve - have an ounce of common sense.
Now a days, there have been an option to change privacy settings on most of the social media platforms but this wasn't present before and also the custom privacy settings are set to all data sharing by default unless you edit these settings. So most of the companies that brought the data from social media companies would already be having everyone's face data.
You are kidding yourself if you think changing your Facebook privacy settings makes any difference whatsoever to your online privacy. It might stop other random Facebook users looking at your photos or your posts, but it definitely doesn't stop Facebook including those data in their profile of you, analyzing it, sharing it, and selling it. Anything you upload to Facebook, even with the most stringent privacy settings, can and will be widely shared with an unknown number of third parties.
smartphones already have this , and they released it because passwords and other security option can be easily bypassed
This is incorrect. A long and random password is exponentially more secure than facial recognition.
