The same dodo Tweeted a ZeroDay on September 9th that crashes ChromeOS and Chrome browsers, and many people who tested it on other mobile Browsers, including Android, found it crashed and/or froze, them, even Brave. Only Safari successfully closed the tab that was frozen, but even that took some time to take.
His excuse for Tweeting it? Google wouldn't pay a bounty for it.
As a software developer, I see nothing wrong with this ;-)
