While the actions are likely temporary, they're one more piece of the growing headache for Facebook since news of the leak broke a week ago. It has faced criticism because CEO Mark Zuckerberg and COO Sheryl Sandberg did not speak out until five days after the story broke.
The company's stock price shed 14 per cent of its value this week. And the grumblings by users, and now, businesses shows no sign of abating.
"The Cambridge Analytica scandal, like many recent headlines coming out of Silicon Valley, raises questions about whether Big Tech is doing enough to balance its own interests with one of its biggest responsibilities: safeguarding your privacy," Sonos wrote in a blog post.
But Facebook downplayed the actions by the businesses.
"Most of the businesses we've spoken with this week are pleased with the steps we've outlined to better protect people's data, and they have confidence that we'll respond to these challenges and become a better partner and company as a result," the company said in a statement when asked about the advertiser.
The fact is, most advertisers need Facebook as a platform because its reach is so great, so any break is likely to only be temporary, said Allen Adamson, founder of brand-marketing consultancy Metaforce.
"Companies can take a short-term hiatus to get some positive spin in the market, but there's no other alternative for digital marketing today," he said. "If you don't use Facebook, the other options are not great."
