Sept. 17 (UPI) -- Ben & Jerry's co-founder Jerry Greenfield quit the company, saying he felt that its parent company, Unilever, was stifling the brand's commitment to public activism.

Co-founder Ben Cohen shared an open letter from Greenfield on X Tuesday in which he said leaving the company was one of the "hardest and most painful decisions" he has ever made.

Greenfield said the company's "independence to pursue our values" was one of the things that was most important to him about working with Ben & Jerry's, adding that independence was "guaranteed when Unilever bought the company" in 2000.

"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," Greenfield statement said. "It's profoundly disappointing to come to the conclusion that that independence is gone."
