These differences have been a continual topic of discussion for the two men as they developed a friendship over the past two years and ultimately negotiated the deal that would make Mr. Koum a multi-billionaire and bring his 55-person startup inside the social network.

Mr. Zuckerberg said he and Mr. Koum first discussed the deal on a Sunday evening less than two weeks ago.

WhatsApp的联合创始人兼首席执行长（CEO）库姆（Jan Koum）一直拒绝在应用程序内引入广告，其主要收入就是用户支付的每年99美分的使用费。

In a December update, Koum said his company's focus was on messaging and only messaging& no games, no advertising, no gimmicks.

在去年12月公布最新数据时，库姆说，他的公司关注的是消息，也只有消息，不是游戏，不是广告，不是华而不实的东西。

In a Tumblr post on the deal Wednesday, WhatsApp investor Sequoia Capital talked about how Koum's experience emigrating to the U.S. as a 16-year-old, and desire to keep in touch with family back in Russia and Ukraine, helped shape his focus on conversations.

WhatsApp的投资者红杉资本周三在Tumblr上发文宣布上述交易时，提及了库姆以前的一段经历，说他16岁移民到美国时，非常渴望与远在俄罗斯和乌克兰的家人保持联络，这使他非常重视对话和交流。

Mr. Koum: We have a shared mission of connecting the world and making it more open.

CEO Jan Koum kept a note from co-founder Brian Acton taped to his desk to remind him of the company's core values. It read: "No Ads! No Games! No Gimmicks!" So the messaging apps have gotten creative.

该公司首席执行官让o库姆在自己桌上一直贴着联合创始人布莱恩o阿克顿留下的一张便条，随时提醒自己牢记公司的核心价值观：“不要广告！不要游戏！不要宣传噱头！”这样一来，短信应用只好想出别的创意。

On the conference call, Messrs. Zuckerberg and Koum said it was important the company operate separately and retain the mentality of a startup, a strategy Mr. Zuckerberg said has worked with Instagram.'

扎克伯格和Koum在一个电话会议上称，保持WhatsApp运营的独立性及其作为初创公司所具有的精神非常重要，扎克伯格称这一策略在Instagram非常成功。
