Google faces hunger strike in China

The protesters also posted an open letter to Google co-founders Sergey Brin and Larry Page asking them to intervene.

"We can hardly believe this was a decision made by Google who always [claimed to] put the interests of customers first and 'Don’t be evil,'" the letter said. 

The companies say they do not understand why Google ended the partnership. They are asking for $7 million in compensation.

According to the article, a Google spokesperson said, "We stand behind our decision."

"We do not discuss individual cases, but there are a variety of reasons why we choose to end relationships with certain partners. In all cases, we do so lawfully and in line with the terms of our contract," the spokesperson added. "We hope to find new resellers to partner with so we can provide even better service to our advertisers."
