更精確的說是不再續發 license，舊的 license 只到 9/30：
Transport for London (TfL), which operates public transport in the capital, has made the decision not to renew the app-based taxi’s license in the city.
The license was renewed in May, but for a period of only five months. It will run out on 30th September, though the company will be allowed to continue to operate during the appeal process.
看起來主要原因是圍繞於 Greyball (利用演算法躲避執法人員的工具)：
According to the TfL regulatory board, the ‘approach and conduct’ of Uber showed a lack of corporate responsibility, which could have resulted in public safety and security issues. It also raised concerns with the company’s ‘approach to explaining the use of Greyball, software that could be used to block regulatory bodies from gaining full access to the app.’
新任 CEO 則是出來道歉：「Uber CEO apologizes for “mistakes” in London」。
