The way mark wrote the email is interesting too. The subject is concised and attention catching. The tone of voice is respectfully. Instead of "How the f you guys can think of selling to Google". Mark assume the rumor was falsed and assume best intention from the Whatapp cofounder. Contrary to the image he built that time (nerdy robot tech CEO 🤓). He is actually a master business leader and emotional manipulator 🤔.
