Engadget – “The only way to opt out is by asking your company’s workspace owner to send Slack an email. Slack trains machine-learning models on user messages, files and other content without explicit permission. The training is opt-out, meaning your private data will be leeched by default. Making matters worse, you’ll have to ask your organization’s Slack admin (human resources, IT, etc.) to email the company to ask it to stop. (You can’t do it yourself.) Welcome to the dark side of the new AI training data gold rush. Corey Quinn, an executive at DuckBill Group, spotted the policy in a blurb in Slack’s Privacy Principles and posted about it on X (via PCMag).
