The marketing and advertising group "Omnicom" has recommended its clients to temporarily halt their spending on ads on Twitter in the short term, according to an internal memo reviewed by Reuters. Omnicom serves over five thousand clients across 70 countries, including McDonald's, Apple, and Johnson & Johnson. The memo did not name specific clients, and it is unclear if any of them have temporarily stopped spending on Twitter ads. This move reflects growing doubts among agencies and brands regarding the future of Twitter since Elon Musk's acquisition for $44 billion. The Tesla CEO attributed the significant decline in revenue to civil rights groups pressuring Twitter advertisers to boycott the service until Musk clarifies how he will manage misinformation and hate speech on the platform. According to the memo, "Twitter's ability to maintain its previous level of brand safety measures and effectiveness appears hindered in the near term." Although Omnicom believes that this is unlikely to significantly increase the risk environment for advertisers, the risk of association with unsafe content may rise and should be considered when deciding on using the platform.
