Open document standards are a great place to start. Any standard format needs to have multiple possible vendors. And I agree it goes further than just document formats. This goes for all important formats, including how software interacts with the operating system. There needs to be other vendors who can supply document editing software that is 100% compatible with MS Office. But more than this, there needs to be other vendors who can supply operating systems that are capable of running Windows software. As long as a single company has the leverage that Microsoft has over the enterprise ecosystem we won't have a free market. Governments can start by mandating that new software deployments have several possible vendors, including at the operating system level.
