Hi David,
The practical implications of this CQ are in our interpretation that it allows Titan to be built on Cygwin if the user so wishes. Cygwin, or parts of it
will not be distributed in any form by Titan.

https://cygwin.com/licensing.html:
Cygwin™ Open Source Licensing Exception
As a special exception to GPLv3+, Red Hat grants you permission to link software whose sources are distributed under a
license that satisfies the Open Source Definition with libcygwin.a, without libcygwin.a itself causing the resulting program to be covered by GPLv3+.
This means that you can port an Open Source application to Cygwin™, and distribute that executable as if it didn't include
a copy of libcygwin.a linked into it. Note that this does not apply to the Cygwin™ DLL itself. If you distribute a (possibly modified) version of the Cygwin™ DLL, you must adhere to the terms of the GPLv3+, including the requirement to provide sources for
the Cygwin™ DLL, unless you have obtained a special Cygwin™ license to distribute the Cygwin™ DLL in only its binary form (see below).
See http://opensource.org/docs/osd/ for
the precise Open Source Definition referenced above.
Our understanding is that this exception prevents tainting of the open source code.
However, I agree this might require deeper legal scrutiny.

This I'd like to give a tentative -1 one to this one -- but depends on some legal interpretations I'm not qualified to make, definitively.
It may be ok, but from reading the license quoted in CQ it sounds like there *might* be some "tainting" of the open source code.
If that's not the case, then fine, it's be ok with me as a "works with".
If that is the case, that there is some "copyleft" implications, then I think that means that commercial products (part of which might be closed source) could not use or build on Titan.
And since that would be a pretty big "change of direction" for Eclipse Foundation, I'd want EMO Director or Board to be involved with deciding that.
