You say that, but Microsoft has contributed to Wine!

Both in terms of code and help, on occasion. Microsoft gave Mono to Wine, and while Wine has a ban on accepting code from people who have seen the source of Microsoft Windows, they have, if I recall correctly, accepted documentation on Windows Internals from Microsoft themselves.

Which is rather kind.

They could of also pulled an Oracle , claimed the APIs are copyrighted and sued.

WINE, even if right couldn't afford to fight.

I can even imagine official Linux support for the Surface tablets.

Infact, Microsoft makes very little off its consumer OS. They could even give up the market entirely and bless a distro with solid WINE support for legacy applications.

They did, well - not the suing part, but everything else in your sentence; including helping Oracle "pull an Oracle". In 2013, Microsoft filed an Amicus brief in support of Oracle's[1] position, appealing against a judges ruling that APIs cannot be copyrighted. At the time, Microsoft were also trying to get an Android-compatible runtime on Windows off the ground, which was incredibly awkward. They came to their right mind by the time 2019 rolled by and the case had been appealed to the Supreme Court. At this occasion, Microsoft switched teams and filed an amicus in support of Google. I don't know if Microsoft's 2016 release of WSL had anything to do with it.
