Sorry but that makes no sense, there is nothing in "Microsoft's kingdom" here, Wine -as you certainly know- is independent. The most Microsoft can do is change the API in backwards incompatible ways - but that'd affect Windows too, so there is little incentive to do that (and attempts such as Metro/UWP/etc to change the core ways of working with Windows didn't prove popular with most gamedevs).
And even if Microsoft does that, it isn't any different than the 2394923th time a library breaks its API on Linux - Linux as an operating system isn't some monolithic project, it is a combination of hundreds of separate projects that for the most part work together like -sometimes misshapen- bricks on a wall. Wine/Proton is just another of those bricks (and history has shown that it tends to be among the more stable ones).
The file format and APIs used are irrelevant as long as the games work. The games work and that is all that matter.
Not when it is a castle on Microsoft's kingdom.
