It's not uncommon for executives of smaller companies to jump ship within a few years of the business selling to a larger firm, whether it's out of entrepreneurial restlessness or unhappiness with the corporate status quo. We don't know which of the two (if any) is a factor with Siri co-founder Adam Cheyer, but tipsters for AllThingsD and Bloomberg still say that he left Apple in June to "pursue other projects." The reported departure follows that of Dag Kittlaus, who quit Apple a year earlier, and should leave the Siri team without the brunt of its early leadership two years after Apple bought the company. Although the impact is uncertain, this doesn't necessarily mean Apple's version of Siri is at risk: along with holding on to any remaining Siri staff, Cupertino will have had a long time to familiarize itself with the code. We'd also take it all with a grain of salt. Apple has declined to comment, and Cheyer's LinkedIn profile still shows him as an Apple employee. Whatever's the truth, the rumor's sources don't have the best timing.
