This is a person who's worked 2 years on a project, in a neglected space where companies don't go because they can't make money.
He deserves praise for taking the time, creating something that's different, and thinking through the idea. Well done!
IMHO this is justified since people often overlook how critical an attack vector this would be.
Imagine if a state-sponsored "hobbyist" posted a pet project like the OP to Reddit and started harvesting keys/password reset capabilities for huge amounts of users.
Hell, people flocked to use unroll.me and then it turned out they were (predictably) scraping your entire inbox and selling the data to advertisers.
I don't believe that worrying somebody's skepticism might hurt feelings is a legitimate reason to downvote (remember, downvotes aren't about whether you agree with somebody; it's about whether they add constructively to discussion).
Aside: Great work OP. Seems like an incredibly hard sector to make traction with though, so best of luck.
No body is detracting anything from anyone but there is no way I’m trusting an application that can take contol of a large portion of my life without assurances.
If your email address gets compromised it’s game over for most people every service you’ve registered with is up for grabs which is also the reason why I don’t recommend anyone to use personal domains for email unless they are willing to pay for it till death do them part.
As time and time again after buying a domain that was used by someone else and setting up a catch all email address I got emails from Twitter, GitHub and the likes.
