Seems an unfortunate state of affairs Here's what the conference said on the matter: https://www.blackhat.com/latestintel/06142019-black-hat-usa-2019-keynote-update.html https://www.blackhat.com/latestintel/06142019-black-hat-usa-... It creates a healthier society if we can listen to people even when we don't agree with their views, thus I am not be in favour of this becoming the norm. It's also deeply impolite to withdraw an invite in this manner when no new information has come to light, merely a change of mind. If he'd been discovered to be dishonest or a criminal that's one thing, but "meh, thinking about it, we don't think we want you to come any more, even though we asked you before, when we did want you to come" doesn't cut it. Will be interesting to see if they stick to the apolitical line consistently with others.
