It's not just Boeing with this one. It's a pattern: Company makes interesting software, becomes somewhat famous. Large company buys small company. Everyone at the small company has a big party, lots of money for many of the people. There might even be plans to support the software. In a few years, the software falls apart to a shadow of what it once was, maybe being dropped, maybe being barely supported for a much larger cost to the users.
The legacy computer companies are known for this, Oracle, IBM, etc.
Hopefully with this one, someone will realize that none of this should be patentable, and someone will develop an open source version that works just as well. They'll still be a market for the old product, though, some people will buy it just because of the SCO, er I mean Boeing, label.
