The antithetic case here has precedence too (node/iojs amongst others) -
"org realizes its share of the base tech has outlived its 'welcome' to no real financial benefit". But I guess a more pressing question is: can a corporate entity be "hands-off" enough so that its subsidiary has room to work as effectively as it had prior to its acquisition?
I don't have the wherewithal to get at these arguments from any angle (and I'm certain I'm missing many others).
Studious maintenance of the base code and branches/PRs besides build tried/true code bases and I hope that we're not being torn of that practice from this buyout; but only time will tell ...
