The reality is that people working on non-google projects keep leaving because the community is being shaped by some toxic personalities. We get hooked by the evangelism, buy the party line, build a proof of concept, become disgusted with the community, leave, and concurrently realize that C++ is the way forward.
Wow, you are the first such example I've heard of. Please email me adg@golang.org. I would be very keen to hear about your experience with the community.
I find it rather rude to publicly say bad things about a community and then not backing it up with at least a subjective detailed report of what happened.
