Re: Evil Neutral
Under Gates, I'd have said Neutral Good.
They ignored laws, were guided mainly by technical expediency. But, for the most part, that worked out rather well for their customers. They made PCs ever-cheaper and easier to use. They resisted the lure of DRM, keeping products like Office and Flight Sim being conspicuously free of creepy malware or dongles. They evolved the GUI while keeping it reasonably flexible, and the kernel to robust multitasking.
Under Nadella, they're clearly Chaotic Evil.
The evil? UWP. WIndows Store. The 'Metro' UI. Perpetual 'updates.' Advertising in the UI. Rearranging the UI for no purpose other than increasing lock-in. Firing their QA staff and shipping buggy updates. Continued use of monopolistic tactics to push products that no longer offer any real improvement in the user experience (e.g. Windows 10).
The Chaotic? Randomly altering and ultimately canceling almost every initiative, including the evil ones noted above, as well as those mentioned in the article, such as Zune and WinPhone, plus some not mentioned so far, such as the excellent Windows CE/Windows Mobile, and the needlessly murdered Flight Sim. (Admittedly, killed by Ballmer, not Nadella.) Spending $2.5 billion for a single videogame franchise. The list goes on and on...
Clearly, both Chaotic and Evil.
