Microsoft has subsidiaries all over the world. They'd still have standing to sue, even if say Germany and France ignored American IP laws( which they definitely won't).
Plus it's not out of the question for them to personally sue WINE contributors. It's not about winning, a simple DMCA takedown notice to any entity hosting WINE code would probably be enough to stop the project.
I want a future of competition between different OSes. I use Linux everyday, but I don't think a market share of 3.86% is sweating anyone at Microsoft.

I could see Lenovo, which is ultimately a Chinese company, making more aggressive steps to offer Linux. But outside of certain ThinkPads you can't even buy a laptop with Linux pre installed.
In my dream world you'd have to buy Windows separately with any hardware. I guess Best Buy could still offer Windows installation as a service though.
