Tesla and SpaceX are among…31 companies that have [joined] an amicus brief against United States President Donald Trump's executive order banning travel into the United States from seven countries. They join the initial 96 companies that filed on Sunday, which included Apple, Microsoft, Google, Facebook, Intel, Airbnb, eBay, Mozilla, Netflix, PayPal, Reddit, Salesforce, Spotify, Twitter, Uber, and Dropbox. The brief says… "The order represents a significant departure from the principles of fairness and predictability that have governed the immigration system …and the order inflicts significant harm on American business, innovation, and growth as a result. [It] makes it more difficult and expensive for US companies to recruit, hire, and retain some of the world's best employees…disrupts ongoing business operations…[a]nd…threatens companies' ability to attract talent, business, and investment…Despite joining the amicus brief, Elon Musk remains on the Trump's economic advisory committee…but said this should not be taken as a sign that he agrees with Trump's policies. [Also refers to: Linux, Red Hat, IBM, Cloud Foundry Foundation, Canonical, and Ubuntu.]
