OK, so here is an "inside" take on it, without breaking my NDA.
All I can say is this. I saw things that certain folk on the ACES team were working on that would WORK WITH FSX and greatly help the community of developers.
I truly hope that those "things" will make it out on the fsinsider or this site, even though the team is sadly gone.
I am going to try to pull some strings in March, that is.... if I can find someones strings to pull
While FSX / FSX1 / ESP2 were in development, there was always the reluctant to release any information, in case it got changed later on.
Now it looks as if it will NOT be changing at all.
Is all this work really just going to be just Archived off, and left in a safe to rot ( outdate & become totally obsolete).
If nothing more than a PR exercise ( and boy, Microsoft do need some good PR at this point), why not release some of this information to the FS Community now.
Give the community something to work with, What is there to loose. ?
To gain ... The community moves forward with new ideas and advances, and then, if at some later date, Microsoft picks up MSFS again, look at all those ideas and developments that are out there for them to "INNOVATE" with, and incorporate into a new MSFS -- all without having to pay their own developemnt team, for coming up with the ideas.
A win-win situation.
Obviously, releasing the FSX source code to the Public Domain would be an interesting situation. I suspect the major reason for NOT doing so, is the reluctance to expose the "Quality" of the underlying source code to the public, rather than its actual IP content.
( I know I would not want to release the source to a lot of the personal stuff I have written, for this reason .. The EXE looks to run "OK", but what is behind it could be embarassing, to say the least.
The Archiving off of FSX, reminds me of the final scene of "INDIANNA JONES" -- having taken so much trouble to find the ARC, it gets burried in a Warehouse, to be forgotten, and hidden from anyone else seeing or using it.
