Slack apologizes after users who travelled to Iran had their accounts shut down

On Wednesday, many users who had traveled to Iran found that their Slack accounts shut down because of U.S. sanctions, even though they did not live in Iran, nor did they have professional links to Iran.
On Friday, Slack sent out an apology to its users and clarified that it did not have information about users' ethnicities, but used location information.
Slack is working on restoring mistakenly blocked accounts and will soon start blocking accounts with IP addresses in an embargoed country.$7 b
