Those sources just say that those companies have some Apple products somewhere in the company. Not that they supply mainly Macs. I work at a very large company that's probably counted here (because the number of Apple devices in the company is not 0), and almost everyone is only supplied with a mid-range Windows laptop, and a cheap Android phone.
