If Google dropped Go tomorrow, there would be immediate backing for newmanagement of a fork.Sure, and we would have Go+, GNUGo, FreeGo (discontinued) and whatnot, each having a different philosophy. There would be flame wars on the internet and nobody would know which kind of Go to use.
Just like any open language implementation out there. CRuby vs JRuby vs RubyMotion vs ... CPython vs Jython vs ... Clang vs gcc vs msvc vs icc vs aC++ vs xlc vs .... Or for that matter Dmd vs ldc vs gdc
