Amazon warehouse workers in Bessemer, Alabama are voting on unionization and Amazon is doing everything it can to stop them. As part of its anti-union campaign, Amazon ran anti-union ads on Twitch, the games streaming giant that it owns. Now Twitch has broken with its parent company and told Motherboard it has removed the ads, and that they should never have run in the first place.

"Twitch does not allow political advertising, and these ads should never have been allowed to run on our service,” a Twitch spokesperson told Motherboard in an email. “We have removed these ads and are evaluating our review processes to ensure that similar content does not run in the future. We are grateful to our community for bringing this to our attention."
