Ben & Jerry’s co-founder Jerry Greenfield is leaving the ice cream brand after 47 years, saying that the independence it once had to speak up on social issues has been stifled by parent company Unilever.

In a letter that co-founder Ben Cohen posted on social media platform X on Greenfield’s behalf, Greenfield said that he felt the independence the brand had to speak on social issues and events was lost to Unilever.

“For more than 20 years under their ownership, Ben & Jerry’s stood up and spoke out in support of peace, justice and human rights, not as abstract concepts, but in relation to real events happening in our world,” he wrote. “That independence existed in no small part because of the unique merger agreement Ben and I negotiated with Unilever, one that enshrined our social mission and values in the company’s governance structure in perpetuity. It’s profoundly disappointing to come to the conclusion that that independence, the very basis of our sale to Unilever, is gone.”

Greenfield said that the loss of independence was coming “at a time when our country’s current administration is attacking civil rights, voting rights, the rights of immigrants, women and the LGBTQ community.”

“Standing up for the values of justice, equity and our shared humanity has never been more important, and yet Ben & Jerry’s has been silenced, sidelined for fear of upsetting those in power,” he said. “It’s easy to stand up and speak out when there’s nothing at risk. The real test of values is when times are challenging and you have something to lose.”

Greenfield noted that Ben & Jerry’s, famous for its colorful ice cream containers with names such as Cherry Garcia and Phish Food, “was always about more than just ice cream; it was a way to spread love and invite others into the fight for equity, justice and a better world.”

A spokesperson for The Magnum Ice Cream Company said in a statement that it would be forever grateful to Greenfield for his contributions to Ben & Jerry’s and thanked him for his service, but was not aligned with his viewpoint.

“We disagree with his perspective and have sought to engage both co-founders in a constructive conversation on how to strengthen Ben & Jerry’s powerful values-based position in the world,” the spokesperson said.

Magnum said that it is still committed to Ben & Jerry’s mission and remains “focused on carrying forward the legacy of peace, love and ice cream of this iconic, much-loved brand.”

Unilever acquired Ben & Jerry’s in 2000 for $326 million. At the time, Ben & Jerry’s said the partnership would help the progressive Vermont-based ice cream company expand its social mission.
