The most painful parts of the Go ecosystem are directly tied to the fact that the Google is making Go for themselves first and foremost and the community is an afterthought.
Google's also opensourced Abseil, their C++ standard library (not meant to completely replact STL, to be clear), which contains all kinds of classes which were copied into many existing Google C++ projects in some form or fashion and sometimes incompatibly (e.g. Google's StringPiece found in several projects).
Either way I applaud them for doing a lot to open source projects. It's not something we can take for granted.
