Never mind Huawei and other Chinese tech companies, it’s Amazon that has become a threat to US national security, according to its cloud rival Microsoft.

That was its response to losing its big defence department contract on Tuesday. The Pentagon announced it was cancelling the highly sensitive, $10bn joint enterprise defence infrastructure (Jedi) cloud computing contract and would start a new procurement process. It said “evolving requirements, increased cloud conversancy and industry advances” meant the Jedi contract no longer met its needs.

That woolly explanation also omits to mention the legal morass that has delayed the contract. It was held up in 2019, when Oracle, one of the original bidders, appealed against the decision to place only Microsoft and Amazon on the shortlist. Then Amazon appealed when Microsoft won the contract.

Yesterday, Microsoft said the security of the US was more important than any single contract: “When one company can delay, for years, critical technology upgrades for those who defend our nation, the protest process needs reform. Amazon filed its protest in November 2019 and its case was expected to take at least another year to litigate and yield a decision, with potential appeals afterward.”

Government procurement processes are already long and legal challenges only drag them out further, so the Pentagon is wise to be pursuing a multivendor strategy now, where everyone can get a piece of the pie and sole contracts are not challenged in courts. It is seeking proposals from both Microsoft and Amazon and will research whether other companies might be able to fulfil its requirements.

Plenty of tech companies ought to be readying a pitch — defence requirements are increasingly moving towards more tech and cyber capabilities, so Jedi is only the tip of a lucrative iceberg. In its statement, Microsoft listed half a dozen other deals with the US armed forces, including providing the US Army with augmented reality headsets in a contract that could be worth up to $22bn over 10 years.

Meanwhile, Amazon’s beef had been that President Trump’s antipathy towards Jeff Bezos had influenced the Jedi decision. Today, he revealed the extent of his resentment towards three other tech leaders, unleashing class actions against Facebook’s Mark Zuckerberg, Twitter’s Jack Dorsey and Google’s Sundar Pichai for alleged “unlawful censorship” of Americans.

Nintendo has announced a new version of its Switch games console, featuring a larger and better display, but the unit is not capable of 4K/UHD on a TV, as had been rumoured, reports The Verge. The screen is 7in, up from 6.2in, and features more vivid OLED technology. There is improved audio, an adjustable stand, a wired Ethernet port in the new dock and 64GB of built-in storage, up from 32GB. It will cost $50 more at $350, with availability from October 8. The original Switch will still be sold, but analysts expect it to be phased out.
