Let's look at who gets what according to the people in this thread who like
this idea:
Benefits
MS: Tools are available to its developers in a somewhat more convenient
fashion than before.
FS: More people migrate to GNU/Linux from windows.
Are we in agreement that MS does not want more people to migrate to GNU/Linux
from windows?
If so, then MS not only feels that this extra convenience is useful for them;
It also means they think it is so useful they are willing to sacrifice some
users for it.
Sacrifice users of Windows for extra convenience that can be had in other
ways? That requires justification. You can't just say 'it benefits both
sides' without actually taking a full accounting; Not if you mistrust MS,
which you've said you do.
Ultimately, the naivete I refer to is rooted in the notion that somehow MS
made the error of not realizing they will lose users.
Give me a single example of such an error in the tech field by a mega
corporation.
If it is not an error on MS's part, you need to explain why the benefit of
this platform is so great they are willing to lose users.
