I understand your confusion.
Let me explain in another way:
I love FLOSS culture.
I love DotA 1.
Being able to play DotA 1 entirely through free software would make me very
happy.
Before Wine, the only method of playing DotA 1 was to have Windows.
Wine is a step towards the desire of mine to be able to play DotA 1 through
free software.
But when you are using Wine to execute proprietary programs, it is still far
from free/open source.
When I see suggestions that may help getting DotA 1 more free, I celebrate.
