Supporting users of Sage who can't use GPLv3+ code was indeed
one of the many many reasons.

You just blatantly made that up!  There is no non-free private release
of Sage that will be made available only for Microsoft.   Anything
the Sage project makes available for Microsoft will be freely available
to everybody.

Are you seriously against being paid to work on free software?

Stockholm, Feb 7, 2002. Torbjorn Granlund, President, CEO, and
Chairman of the Board, of SWOX, the worldwide market leader in
compiler technologies and specialized software, will head the new
merged entity, that will maintain the name SWOX. An excited Mr.
Granlund comments "This acquisition will allow us to further extend
our lead in the custom software compiler area, and facilities our
accelerating growth in a challenging economic environment".

You made up these assertions about there being a closed release.
There is and never has been any plan to make a "closed release".
